What is a test and testing?
Testing is a test that allows you to determine whether the actual behavior of a program corresponds to the expected behavior by running a specially selected set of tests.
A test is the fulfillment of certain conditions and actions necessary to test the operation of a function or part of it.
How many tests do you need?
The tester prepares a set of tests (check-list), based on the specification for the program. To connect the testing specialist is necessary at the requirements development stage. After spending a little more time on the finalization of the documentation, it will be possible to avoid the much higher costs of rewriting the software in the future. The process of selecting tests is reminiscent of collecting: we need a complete collection but without duplicates.
- stored in Test link – for manual testing;
- Or programmed in special frameworks – for automated.
In general terms, testing is as follows:
- The program and requirements come to the tester.
- He performs the necessary operations, monitors how the software performs the tasks.
- Based on the results of the audit, a list of correspondences and inconsistencies is formed.
- Using the information received, you can either improve the existing software or update the requirements for the program being developed.
Testing in the context of the overall development process
Usability testing (ergonomic testing) helps to determine whether a site or user interface is convenient for its intended application.
Creating a checklist – preparing a set of tests, making the necessary proposals in the developed requirements (in terms of quality).
Testing. Having received the program ready for verification or a part of it, the specialist checks its compliance with the requirements for the selected set of tests. In case of detection of defects, it gives developers a set of tasks necessary to improve the product to the state of compliance.
Verification is a test that shows whether the errors found in the tests were corrected. It is usually closely associated with regression testing. Regression testing (regression testing) is directed to the detection of defects in the code sections that have already been tested. Allows you to catch regression errors (when after making changes to the program, the things that worked before cease to work). Although such tests can be performed manually, more often specialized programs for automated testing are used for this.
Performance test (performance testing) is performed on the stands, where will continue to operate the software. The goal is to identify the problems of the stand (not software), to simulate the work of users, to test for stress resistance. It makes sure that the application/system will cope with the real load in the future.
The Benefits of Testing
Without checking the program for compliance, you do not have to talk about its quality, so Software testing is an integral part of the development. And the earlier a quality control specialist is included in the development process, the more highly-qualified the product is at the output.
