Performance Testing of e-commerce Applications – Key considerations

Who would not wish to attract heavy traffic on their app, especially when it converts into great revenue? Wishes can come true if you properly testand optimize applications to perform. You have to be extra careful when it comes to e-commerce applications. You might launch a new product on your app or announce a discount on it but if the high traffic mars its functional efficiencythen it will crash. This will prove counter productive for a business; your e-commerce app is critical for your growth as well as reputation.

Testing your Ecommerce App

You can test your applications either through performance testing or modeling. Modeling is a method in which the entire scenario is simulated and a ‘what if’ condition is created with the help of a software. On the other hand, in the performance testing method, the application is run on a system and there are devices to monitor its performance. The app is tested on a controlled software to test its efficacy in a larger environment.

Performance testing includes a range of different kinds of tests that are carried out to analyze the different aspects of an application. One of the ways in which performance testing is carried out is through load testing, wherein testers try to evaluate how the app will perform when the number of users as well as the number of transactions increase significantly. You can fix any issues that are raised during the testing so that when the application is launched it performs as per expectations.

Why Test the Performance of Your App?

Performance testing helps you understand the behavior of the application under load conditions. The speed at which it responds, the conversion of incoming traffic to revenue etc are all assessed during performance testing of the app. Some of the other benefits of performance testing include:

  • Discovering and fixing any defects – Whether the defect is in the coding infrastructure of the app or in the way users interact with it, with performance testing you are able to detect it much earlier and fix it. The app when launched in the market is perfect and performs to its utmost capacity.
  • Hardware requirements – Performance testing allows you to understand the way your app will react to increased traffic volumes or slow server speeds or network issues etc. You can thus make the required changes to the hardware requirement for your app. This saves you a lot embarrassment at a later stage if the app does not function properly.
  • Confident release – All in all it helps you to be confident about launching an application that will not disappoint the users. When the results have been tested and analyzed before hand, you know that the application will achieve its aim in a trouble free manner.

Performance Testing for Your E-commerce Apps – Doing it Right

Having seen the advantages of performance testing, let us see the right way of doing the testing.  For this, the test environment plays a critical role and needs to be as close to the real environment as possible. Speed, scalability and stability are the three aspects that should be tested before launching.

  • Test conditions are influenced by both the hardware and the software. However, it might not be possible to simulate the entire environment for reasons of the finances involved. In this case a better alternative is to scale down the project and its conditions and then test it.
  • An e-commerce app should be designed such that it can be easily accessed by prospective customers anywhere on the globe. Testing needs to be done to ensure that the app performs across the world. This increases the number of variables like operating system, device, browser etc that are to be considered for efficient functioning but then the app has to function perfectly irrespective of who the user is.

On many e-commerce apps, the traffic is not converted to revenue because the users leave before placing the order. This could be because of the speed so it is important that the app responds quickly as per the user feedback.

Quick Guide to Dependency Structure Matrix – Why is it Must in Testing?

With the advent of technology and changing work scenario, more and more organizations are running multiple programs and projects in parallel. In most cases, such programs and projects aren’t completely isolated. Rather, they are dependent on other programs and projects within the organization. What’s more, they get affected by changes to the schedule, type, budget, risk and/or scope of those programs and projects. Thus, it has become important, more than ever, to be able to understand these dependencies and evaluate the impact of such changes. With the dependency matrix in place, testers can analyze these “what if” scenarios better, thus giving them a precise visualization of the dependency of programs and/or projects on others and testing how changes in one project or program will affect the others.

Changes – A Vital Element of Software Development

By its nature, software tends to change throughout its life cycle. Thus, it’s no wonder that unless a close eye is kept on how it reacts to changes or if its relation with other projects and programs has changed due to some changes in those, it won’t function properly and may even deteriorate, quality-wise. After all, the quality of software dependencies has a huge impact on software re-usability, understand-ability, test-ability and maintainability. That’s why software faults are often triggered by violated dependencies that aren’t recognized by the developers, or found and fixed by the testers. Since the impact of syntactic, work and logical dependencies on the failure proneness of a software system/program is significant, testers have to resort to dependency matrix.

Software Dependencies

Logical Dependencies: These are related to source-code files that are modified jointly as part of a modification request (MR). It’s important to note here that in case an MR needs only one file to be changed, no dependency would arise. Testers evaluate such dependencies between the source code files by identifying source code files that got changed mutually as part of software development. While testing logical dependencies, those that aren’t covered or visible in syntactic dependencies are identified. Clustering/Number of logical dependencies come under the purview of testers in these cases.

Syntactic Dependencies: These could be inflow/outflow of functional or data dependencies. Such dependencies are evaluated between source code files by spotting function, data and method references crossing every source code file’s periphery. Such testing emphasizes on checking the relationship between dataflow and control.

Work Dependencies: These are usually related to coordination requirements or workflow. Such dependencies are triggered by organizational and human factors, on which the software systems’ failure proneness depends. Usually, improper/lack of proper coordination and communication between developers, testers, QAs and IT infra give rise to problems related to work dependencies, which is why testers need to find them out and fix them.

Data Dependency:
From unauthorized data access and data manipulation to database error, stealing of confidential data by bypassing access controls etc, security testing has to check a lot of parameters related to data. No wonder that security tests have to check data related dependencies where a specific data structure gets modified by a function and is subsequently employed in another function.

Functional Dependency:This refers to how elements behave in relation to others, especially when a change in one (such as the resolution of a defect that a developer had earlier encountered, or the development of a new functionality) affects the functionality of the others coupled to it.

Advantages of Dependency Matrix

  •  Helps in decision making: In test execution cases, it helps us decide whether to proceed or not.
  •  Helps formulate regression test requirements: When any functional requirement undergoes a modification, this matrix helps in identifying the affected modules, thus letting one arrive at the regression test requirement.
  • Quick and precise estimation: With dependency matrix, you can evaluate estimates quickly and precisely.
  • Easy detection of data related failures: Dependency matrix helps in identification of data related failures easily.

Since dependency matrix is information-flow oriented (not time and schedule flow oriented), it helps in analyzing and improving the design and development processes, along with spotting and fixing of project/program roadblocks and bugs. This in turn helps boost quality of the end product, cut costs and decrease the time to market a quality product.

A/B Testing – Where are you going wrong?

A/B testing also known as split testing or bucket testing is a fantastic way to test two versions of a webpage or an app before launching one of them. The developers want to understand the end users’ reaction to both the versions so they can modify things and launch the popular one. Data like page views, conversion and other statistics are the variables that are used in the A/B testing. This surely must spell success but even after all this there can be errors. Let’s have a look at some of these common mistakes and understand how they can be avoided.

1. Testing early on in the process

Deciding whether A is better than B is based on statistical analysis. If you test the two versions early on in the process, the results you will get are inaccurate. You might be tempted to decide in the favor of the version that has got 75% positive results but experience will tell you that it is not reason enough to decide. There have been instances where the reality check is proved wrong after this kind of weight age in favor of one. The only way the A/B test will give accurate result is when you reach the truth regarding popularity of the versions.

2. Duration of test is not completed

Any test has to be run for its full term. Even if the test is done on a high traffic site, you cannot decide between A and B depending on the first few days of results. Even if your expected goals are achieved you cannot stop a test mid week. It has to run for a full week until you find a winning combination fro you never know some audience might check in after you stop the test and change the results completely.In any case, the conversion rate is dependent on the day of the week therefore running a test for the full week takes care of the ‘seasonality’ factor.

3. Testing with inadequate traffic

If you run the tests when there is not adequate traffic on your site, the results that you get cannot be believed. For instance, if you have made 2-3 sales in a month and with your version B you have got 4 hits, you might think it is better to run the test for a longer duration of time to get the statistical guarantee. With inadequate traffic on the site, this test result will be time consuming and ultimately show on the revenue. Instead it might be better to shift to B in the first place.

4. Test designed for anything or nothing

Testing should not be done just for the sake of it. The test itself might not have been designed to guarantee results that can be quantified and used by the company. A random test where you do not have an idea of how the results will benefit the company will not help the business anyway.

5. Testing the obvious

There are some aspects of your product or site which are universally accepted facts. They have been proved times and again so there is no need to waste time and money trying to prove them for your company. These should be integrated in the design already and the test should be on aspects that are critical to your company or have been customized by you in order to understand the customer response.

6. Test A/B at different times

The results of A/B test is not valid if they are carried out at different times. This is because there are too many variables in a test that change with time. The audience and its requirement for instance will change with time so you will not be able to decided between A and B. It is advisable to divide the audience into two and run the two versions at the same time.

7. Not segregating the variables

Not being able to differentiate between behavioral pattern of the basic variables can lead to disaster. For instance when a test is conducted there will be some first time users and some returning users. The feedback that you will get from the former is different from that what you will get from the later. Though both need to be taken into account, the data from both has a different kind of role to play in the outcome of the product so you need to segregate them and collect data.

Staying Ahead in Changing Times of Software Testing

Practices in the software world including testing are changing at a fast pace. In the beginning, testing was done at the end of the development phase like a reaction to what the developers had put forth. Not anymore. These days testing is involved from the start in every possible way right from the use of tools to the methodology to using user feedback etc. Having said this, let’s take a look at some of the factors that have contributed to this shift in focus and those that will help you move up in the competition.

Testing Transformation for all companies: How to change the way you perform testing today

SMAC testing

Social media, mobile, analytics and cloud technologies together are referred as SMAC. It is much in demand these days because of the significant role it plays in improving operational efficiency and strengthening the user-designer link. Mobile, cloud and social media are an integral part of all businesses and thanks to these; a small error in the program or the system can be exposed to a global audience. Testing on these platforms has grown in a big way with larger amount being allocated to them in the budget.

Adapting Cloud migration

Cloud computing as a concept was not well received initially. However over the last year it has bounced back and at present has a reach of about 32% and growing steadily. Testing in cloud environment is easy from the tester’s point of view as well and organizations will have to equip themselves to make use of this opportunity.

Test automation & its future

When you talk about functional testing, you think about test automation. If programs can be developed which can test the project on their own, then you get improved efficiency. Test automation strategy that can ensure that you get quality software at a much faster pace will definitely put your organization ahead in the competitive market. The framework should be thus developed that it allows testers to test applications in an automated machine but from the user’s perspective

Moving shift left in testing

Shift left is the latest concept to have hit the field of testing and is considered important from the point of quality assurance. It allows testing to be performed earlier in the project lifecycle. On the project timeline, it is literally shifted to the left towards the beginning of the project and hence the term shift left testing. This concept is helpful because it takes care of all the disadvantages that the earlier method of late shifting had. As a result of this –
1. Testers are now more involved in the initial project planning and have a say if they feel that the testing resources seem inadequate.
2. Basic design defects in the project can now be nipped in the bud instead of the earlier methods in which the testers were given the finished project and the whole process had to be reworked after the defect was uncovered.
3. As the project progresses and more and more software programs are integrated into it, debugging by locating and isolating the fault becomes complicated. By shift left testing the tester is involved from almost the beginning so debugging is not as complicated.
4. In the earlier method when testing was done in the end, there was a rush to meet the deadline and launch the program. As a result there was little time to fix the bugs. Most of the times, the project was launched with the bugs and fixing postponed for a later version. This postponement leads to great backlog as far as testing is concerned especially if the project is too large. Shift left testing allows testers enough time and launch a fool proof version.

The days ahead for the testing industry are definitely bright. The testers will have enough and more opportunities at proving themselves in the testing industry which is 13 billion dollar strong and growing every minute.
