Parallel software testing

In traditional test environments, testing is manual and sequential. Problems often outnumbered solutions, and software went to market with built-in issues. Companies may have been aware of some, but may not have had the resources time or money to resolve them.

Fully embracing automatic testing results in slackness and reticence, particularly because of its high costs. Parallel testing is a semi-automated testing process that relies on cloud technology and virtualization to perform tests against several configurations at the same time. The goal of this process is to resolve the limitations of time and budget while still assuring quality. The parallel testing process can apply to a single application or to components on multiple platforms.

Each application or subcomponent, such as operating systems, browsers, and any combination of them, can be tested on a different computer. While test computers can be individual hardware units, parallel testing more commonly refers to using separate virtual machines within the cloud. A virtual machine is an emulation of a computer system, based on computer architecture, and it provides the same functionality of a physical computer.

Whether your testing machines are real or virtual, parallel testing runs more tests than would be practical with sequential testing. The automated part is the test software that connects the master computer with N-controlled machines that run and test the various test environments.

Understanding what parallel testing is, requires knowing what it is not. Parallel testing is a process, or framework, for testing, and it should be used as such. It is not a subset of software testing, only a tool within the larger testing toolkit. It also is not an add-on to your pre-existing testing regime.

Neither is it a set of final spot-checks. Instead, the parallel testing framework should contain all or close to all of the required sequential tests. Because parallel testing relies on running virtual machines in the cloud, invested testing time can be divided by the number of test machines — so testing time can easily be a fraction of what it is in traditional, sequential testing.

While parallel testing reduces the time and money invested in testing, there are plenty of other benefits to using parallel testing.

Thus, additional help may be needed during this transition phase. When needed, managers within the organization that have acquired more experience with the new system, or vendor representatives, may provide assistance by answering any questions and providing information.

Running parallel testing during cycles in which there are numerous salary increases or several new hires may needlessly increase the likelihood of errors. Running parallel testing during cycles in which there are less than the standard number of payroll transactions, such as the holidays, may not give an adequate representation of how well the system will perform during normal payroll cycles.

The standard number of payroll cycles used for parallel testing is two. It is best for these two payroll cycles to be completed consecutively. This will ensure that all errors can be spotted, corrected and re-run immediately. Organizations have different needs and capabilities, however, so the optimal time and methods for parallel testing may vary. Once parallel testing has been run for one payroll cycle, the results from the new and legacy systems should be compared line by line. Every discrepancy found should be highlighted and categorized according to the cause of discrepancy.

After categorizing these inconsistencies, the discrepancies or the cause of the discrepancies should be corrected as soon as possible. This will allow further parallel payroll testing to produce more accurate results. If there are unexplainable errors, parallel testing should continue until the errors can be clarified and rectified.

Any selection can alter the way your company handles its greatest asset — your employees — for years to In such cases, testers need to do the parallel testing, in order to evaluate that data migration is done successfully. Also to check whether the changes in the new version does not affect the system function. The tester must verify that changes are executed properly, and the user is getting the desired output as per the requirement.

For performing parallel testing, you can simply create several project that will test a different part of the application Slave Projects and one project master project that will run these projects.

Parallel test entry criteria define the tasks that must be satisfied before parallel testing can be efficiently executed. Run multiple scenario cycles using pre-defined test data, which was pass from the previous system. When we run the parallel testing cycle, the results of both the new and legacy systems should be measured line by line with differences highlighted.

Every difference which we captured should be defined as per the type of error. Skip to content. Report a Bug. Previous Prev.
