Using Apache Bench for Simple Load Testing

If you have access to a Mac or Linux server, chances are you may already have a really simple http load generating tool installed called Apache Bench, or ab. If you are on windows and have Apache installed, you may also have ab.exe in your apache/bin folder.

Suppose we want to see how fast Yahoo can handle 100 requests, with a maximum of 10 requests running concurrently:

It will then generate output as follows:

As you can see this is very useful information, it returned requests at a rate of 52.94 requests per second, the fastest request was 175ms, the slowest 224ms

So the next time you are tempted to whip out cfloop and GetTickCount to do some benchmarking on a piece of code, give ab a try, it’s easy to use, and will yield much more realistic results.

Because ab supports concurrency, this has two big advantages over cfloop. The main one is that it allows you to test how your code runs concurrently, this can help you identify any possible race conditions, or locking issues. Concurrent requests are also a more natural simulation of load than loops.

Suppose you wanted to test multiple url’s concurrently as well? You can do this by creating a shell script, with multiple ab calls. At the end of each line place an this makes the command run in the background, and lets the next command start execution. You will also want to redirect the output to a file for each url using filename For example:

The usage info from the ab version installed on my Mac (v2.3) is listed below. As you can see there are many useful options for outputting results, and sending additional data in the request.

Pete, I like your suggestion, by your method is completely incorrect. First, benchmarking Yahoo.com is useless for detecting their performance, as there are too many other variables to take into account. Second, your scripts will not gather correct result for two reasons: 1). You are benchmarking localhost, that will spike the load on the box, making the performance less accurate. and 2). You are running multiple benchmarks concurrently, which will also skew your results. You should always run your benchmarks from another machine, and run one at a time to isolate performance, all you’re doing right now it wasting electricity and getting useless results.

hello pete, while i was trying to use the ab cmd,i could not get my ip addr either by ipconfig or /sbin/ifconfig -a the problem is i get different ip addr’s. how should i check the performance?

Software Testing QA Tutorial

A website which provides essential Software Testing Tutorial for QA and Testing enthusiasts.

Some of the Priority Areas Software Testing Tutorial are as below

Includes topics related to the General Testing Terms, the different Type of Testing, the Test Life Cycle and Testing models, the Bug Life Cycle, the various Test Design Techniques and the software Testing Process.

Software Test Management

Includes tutorials on Software test estimation, Testing Metrics, the various software testing metrics, the effect of CAPA in software testing and the various verticals in Software Testing.

Some of the areas covered under Software Test Automation include Automation Process, Automation Framework, QTP Tutorial and QTP Certification questions.

Majority of the Interview Questions related to Manual Testing are also covered.

Software Testing has gained a phenomenal importance in the recent years in the System Development Life Cycle.

To paraphrase Feigenbaum [Feigenbaum, 1991], Quality is the ability of a system to meet user expectations.

Software Testing

It is the process of testing the functionality and correctness of software by running it. Software testing is usually performed for one of two reasons:

– Reliability or Process of executing a computer program and comparing the actual behavior with the expected behavior.

Software Testing is not an activity to take up when the product is ready. Effective software testing begins with a proper plan from the user requirements stage itself. Software Testing is an integral, costly and time consuming activity in the software development life cycle.

In the software testing phase a application or product undergoes various types of software testing before it is shipped to the customer or end user.
There are about 50 types of software testing which are available. Software Testing has a different philosophy compared to other activities in the development life cycle.

Software Testing is not a technique for building quality systems; rather, it is a technique that is used because we recognize that we have failed to build a defect free system or application.

Software Testing is a verification method that applies a predefined set of conditions for the purpose of finding defects. Software Testing is a process of executing a program with the intent of finding errors.

There may be many definitions of software testing and many which appeal to us from time to time, but its best to start by defining software testing and then move on depending on the needs.

As per IEEE 83a – Software Testing is the process of exercising or evaluating a system or system component by manual or automated means to verify that it satisfies specified requirements.

Software Testing Rules

– Perform the software Test early and test the software often.

– Integrate the application development and testing life cycles during software testing.

– Formalize a Software testing methodology; This will help test everything the same way and help with uniform results.

– Develop a comprehensive Software Test plan. It forms the basis for the Software Testing methodology.

– Use both static and dynamic testing during the software testing phase.

– Define the expected results early during software testing.

– Understand the business reason behind the application or software on which you are testing. You’ll write a better test cases or scripts.

– Use multiple levels and types of testing (regression, systems, integration, stress and load) during the entire software testing cycle.

– Review and inspect the work.

– Don’t let your developers check their own work during software testing. They will miss their own defects.

Leak Detecting Services

How to Find a Water Leak

Our highly trained engineers at L.D.S. Leak Detection Specialists Ltd. will choose the approriate testing and inspection process specifically chosen to suit your home or commercial business to find the leak.

Our engineers at L.D.S. carry all the latest technology in leakage detection. We have listed the main Leak detection methods and equipment below. Inspection cameras. Protimeter mms damp meter survey kits, pressure gauges both hydraulic and digital and salts diagnostic kits also form part of the L.D.S. engineers equipment.

Leak Detection Methods to Find A Leak

Acoustics
Acoustic profiling uses ground and pipe sensitive microphones to enhance the sound of the leak. This method can help in pinpointing precise leak location.

Correlation
Is a way of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure creates noise that travels through the pipe walls, the surrounding ground and along the contents of the pipe. Correlators are a very accurate sound testing device which are used to identify the acoustic frequency caused when a pipe is leaking. The correlator uses two identical sensors located along the pipe to calculate the leek location by logging the signal delay, sensor distance and the sound velocity.

Tracer Gas
The trace gas, a safe mixture of hydrogen and nitrogen, is introduced into the pipe with the suspected leak. The gas, is the lightest in the atmosphere and is made up of of small molecules. The gas will exit at the leak and make its way to the surface where it is detected using gas sensitive detection pobes.

Thermal Imaging
Thermography is the use of an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermography cameras can identify problem areas that can’t be seen with the naked eye, detecting hidden water leaks. The infrared inspection camera can detect not only hidden water leaks and their origin, but also moisture that cannot be physically reached with moisture meters. Read more

Pipe, Cable and Metal Detection and Tracing
Often the exact position of pipes and cables is unknown due to innacurate or non existant network plans. In order to carry out precise water leak detection and to avoid damage to utilities and operators during excavations, it is essential to know the precise position of all services. We use high performance equipment which can locate and trace buried pipes and cables.

Network Monitoring with Noise Loggers
Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources. In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Read more .

Software Testing Effort Estimation #load #testing #example


#

This topic is a mixture of practical experiences and estimation theory (estimation science, theoretical knowledge). The purpose of this topic that the Test Leads, Managers or aspiring leads, managers must aware of all the test estimation techniques. This will helps in clearing interviews and in test planning as well. In the upcoming topics we will discuss the Guidelines and Principles for Test Estimations.

Introduction – Estimation is done often because it is expected to help in predicting how much will the project cost and when will the project get completed. Proper analysis and effort estimation is necessary for successfully planning for a testing project. Any flaw in critical estimation phase, results in missing the project deadlines, reduces ROI and loses of customer s faith. Remember – Bad estimation can lead to poor distribution of work.

There are different standard and non standard methods for test estimation. In many product based companies, people utilize non standardized but conventional estimation methods to make things work. These methods might have developed over a continuous period accommodating hidden factors like nature of application under test, environment, and risk factors for that specific product/market. But these methods can t be adopted as a generalized organization standard for a mature operation model.

Fact: Managers/Leads are not comfortable with software estimation work. But it is a required activity, so based on their past experience on one particular Product, Test Leads/Test Managers estimate the entire testing project (but for that Product only). Because they spent 1-2 or 2-3 or even more years on that particular product. But if they are asked to change company or shift to new product of entire different domain, then it is very hard for them to do estimation.
In this topic, we will discuss following methods for test estimation:
1. FIA (finger in the air) or best guess
2. Ad-hoc method
3. Experience Based – Analogies and experts
4. WBS
5. Delphi technique
6. Three-point estimation (successive calculation)
7. Function points / Test point Analysis
8. Percentage of development effort method
9. Percentage distribution
10. Use case point estimation method

Lets discuss one by one:
1. Best Guess This technique is purely guesswork and based on the some sort of experience.
The method is very common, but since it is based on your gut feeling, its uncertainty contingency is probably around 200% or even higher.

2. Ad-hoc method – The test efforts are based on tentative timeframe. The timeline set by managerial or marketing personnel or by client without any guess/experience. Alternatively, it is done until the budgeted finances run out.
This is very common practise in extremely immature organizations and has error margins of over 100% at times.

3. Experience Based – Analogies and experts:

  • Metrics collected from previous tests.
  • You already tested similar application in previous project.
  • Inputs are taken from Subject Matter experts who know the application (as well as testing) very well.

4. Work Breakdown Structure – It is created by breaking down the test project into small pieces. Modules are divided into sub-modules. Sub modules are further divided into functionalities and functionalities are divided in sub-functionalities.
Review all the requirements from Requirement Document to make sure they are added in WBS. Now you figure out the number of tasks your team needs to complete. Estimate the duration of each task.

5. Delphi technique Same as above WBS. Here functionalities and each task is allocated to each team member. Then team member gives estimate that they will take this much hours to complete the task.
Averagely, this technique gives good confidence in the estimation. This technique can be combined with other techniques.

6. Three-point estimation This technique is based on statistical methods In this technique, task is broken down into subtasks (similar to WBS) and then three types on estimation are done on each chunk

  • Optimistic Estimate (Best case scenario in which nothing goes wrong and all conditions are optimal.) = a
  • Most Likely Estimate (most likely duration and there may be some problem but most of the things will go right.) = m
  • Pessimistic Estimate (worst case scenario which everything goes wrong.) = b

Formula to find Value for Estimate (E) = a + (4*m) + b / 6
Standard Deviation (SD) = = (b – a)/6
More information about this technique can be find at:
http://www.projects.ed.ac.uk/methodologies/Full_Software_Project_Template/EstimationGuidelines.shtml

7. Function Point/Testing Point Analysis: The FP technique is a direct indicator of the functionality of software application from the user’s perspective. This is the most accepted technique used to estimate the size of a software project.
This technique is a part of TMap. Base of this technique is function point technique. Here we convert function points into test points. In Test Point analysis, we usually carry out the following:

  • Dynamic Test Points
  • Static Test Points
  • Environmental Factor
  • Productivity Factor
  • Primary Test Hours
  • Control Factor
  • Total Test Hours

You can download the detailed self explained presentation here
http://www.eurostarconferences.com/community/member/eurostar-presentations-archive/test-effort-estimation-with-test-point-analysis.aspx

In Testing, This estimation is based on requirement specification document, or a previously created prototype of the application. To calculate FP for a project, some major components are required.
The major components are:
Unadjusted Data Function Points: i. Internal Files, ii. External Interfaces
Unadjusted Transaction Function Points: User Inputs, ii. User Outputs iii. User Inquiries
Capers Jones basic formula:
Number of Test cases = [Number of Function Points] x 1.2
Total Actual Effort, TAE = (Number of Test cases) * (Percentage of development effort /100)
This method is done in a case when a detailed low level design document or requirement document is available (i.e measure of function point is available) Previous data for development and testing is available. But now days, when we are using agile and iterative methodologies to deliver projects, so most of the times all this documentation is not available.

8. Percentage of development effort method
Here the assumption is that a more complex business application may require more testing effort. The test effort required is a direct proportionate or percentage of the development effort.

Note: The development effort can be estimated using line of code (LOC) or function point (FP) which is not in the our scope.
Example:
If a previous project with 500 FPs required 50 man hours for testing, the percentage of testing effort is calculated as:
P = (50 / 500) * 100 =10%
For the current project with a development effort, say 1500 FPs, the testing effort is:
Total Actual Effort, TAE = 1500 * (P/100) = 1500 * (10/100) = 150 man hours.

9. Percentage distribution Here all the phases of SDLC are divided in parts and assigned effort in %. Like
Project management 7%
Requirements 9%
Design 16%
Coding 26%
Test (all test phases) 27%
Documentation 9%
Installation and training 6%
Now testing % is further distributed into all testing phases:

10.Use case point estimation method: Use case point (UCP) method is gaining popularity because now-a-days application development is modelled around use case specification. The test case development is normally kicked off after baseline use case. So the various factors in use case give a direct proportion to the testing effort.
Use case is a document which well specifies different users, systems or other stakeholders interacting with the concerned application. They are named as Actors . The interactions accomplish some defined goals protecting the interest of all stakeholders through different behaviour or flow termed as scenarios.

UCP Estimation Method in brief
1. Obtain unadjusted actor weight (UAW)
2. Determine unadjusted use case weight (UUCW)
3. Calculate unadjusted use case points (UUCP) UUCP = UAW + UUCW
4. Determine the technical/environmental factor (TEF)
5. Compute the adjusted use case point (AUCP) AUCP = UUCP * [ 0.65 + (0.01 * TEF)]
6. Arrive at final effort using a conversion factor Total Actual Effort = AUCP * CF

Conclusion
There can t be a sole hard and fast rule for estimating the testing effort for a project. There may be different other methods also which can be effectively used for the purpose. It is recommended to add on to the possible knowledge base of test estimation methods and estimation templates constantly revised based upon new findings.

Automated and On Demand Load Testing

“We recently rebuilt our website to provide Virgin America customers a far easier, more intuitive, and fun online booking experience. High capacity planning, stress testing our booking purchase flow, and overall performance optimization were critical before the big launch. Apica’s team worked hard to ensure our site lived up to its “faster, smoother, and more intuitive” promise. They handled all aspects of testing from start to finish, both helping us pinpoint our greatest bottlenecks and translating test metrics into actionable insight for our development team. Their advice saved us countless hours troubleshooting and helped us avoid any post-launch performance snafus.”
Tony Vela
IT Manager, Virgin America

“As a gaming company, we have extremely tight turnarounds for each release. Come launch day, if the game isn’t performing well, most players will never come back again. Apica not only provided ongoing load testing and valuable performance recommendations for our Call of Duty “Ghosts” companion app, but created a custom SDLC platform to augment our internal QA resources. You don’t want your developers writing tests – it is a huge resource constraint to expect them to do so in addition to their other work. Apica was instrumental in our resource planning.””
Keith Miller
Technology Director, Activision Beachhead Studio

“As our web site gulfnews.com becomes an increasingly important part of our business, ensuring world class Web Performance becomes a must. Working with Apica has proven to be an excellent choice for us. They have specific expert knowledge of our platform, they have completeness in the service offering which minimises potential undetected problem areas, and finally, being a fast and agile company, they can give us the attention we need when we need it. What really counts in the end is the question whether we have better web performance now than before the project, and I can safely say – yes we do.”
Fadi Issa
Service Delivery Manager for Corporate Digital Media

The Apica team worked closely with our engineering team to simulate a very complex set-top box environment. They not only provided incredible loads and quick results but they also provided great insight on various configuration settings. If you want someone who is committed to your success then I highly recommend you go with Apica.
