Why Do Top Testing Companies Use Test Cases

While verifying the functionality of a software program, testers use test documentation, which contains a detailed information, so called artifacts, on how the application should work and how it is likely to work. The development of these artifacts takes place before or during the product’s testing. This documentation can cover the whole software testing life cycle and is meant to be used for testing the next version of the app.

Testing documentation is an entire suite of artifacts which describe test plan, test design, test procedure, test summary report. It is used by quality assurance organizations, including top testing companies to better manage the whole test process. The documentation also serves as a checklist of different activities which need to be taken into account during a test project. Each test documentation includes test cases which describe an expected behavior of the system under specified set of conditions.

Test Cases are Used for Various Types of Manual Testing

• functional testing;
• acceptance testing;
• load or stress testing;
• exploratory testing;
• smoke-testing.

However, software engineers tend to automate their tests cases and by doing so they can execute these over and over again. Test automation companies run different tests in an automatic way so that to increase efficiency, effectiveness, and coverage of software testing.

Besides, it has become common to use test management systems (tools) for developing test cases and carrying out testing process and also managing both manual and automated test cases. These help to boost design & testing teams productivity and ensure real-time visibility into the level of quality of software products among all participants of the project.  

Test cases are indissolubly related to the requirements specification they can be derived from. Changes in these requirements should be timely reflected in the test documentation with the help of software development management system using the trace mechanism for analyzing test results.

When running a test, software tester executes one single testing step of a test case or the whole test case and records the results, attaching bug reports and other supporting information: screenshots, dumps, logs, etc.

It Can Be:

• beta testing;
• deployment testing;
• acceptance testing;
• usability testing;
• configuration testing;
• security testing.

Manual testing is known to be a routine and time-consuming process that is why it is not easy to hire software tester to do this kind of work. Most testing specialists prefer to get involved in automated testing.

Test Automation Allows You to:

1. Leverage testing resources, increase test coverage.
2. Lower number of defects before they reach production phase.
3. Speed up time-to-market.
