How to Cope With Incomplete Test Coverage?

The test coverage is a very important indicator for a software test team. The specialists try to cover the most part of the various system aspects by the tests in order to improve the product quality.

This requires a certain preparation and planning. Software product testing – a rather complex and multilevel process. First, software testing company specifies the scope of test coverage in such a way to fully cover the system functions. It includes not only the main functional but also all possible limitations.

The next step: to reveal how to check the product activity, to examine all characteristics and limitations of the system.


A specialist may also use these data, conducting functional testing, test case optimization or regression testing.

After approving the scope of work, a tester may proceed to writing the test scenarios for each system feature, basing on user stories. The code writing itself and test creation should be fulfilled simultaneously.

For the QA specialist, it is of great importance to create enough number of tests for the execution of all main types of product quality checking.

What Types of Testing Should Be Performed for the Full Test Coverage?

  • Positive testing
  • Negative testing
  • Performance testing
  • Supportive testing (for example, login procedure testing, auditing, data integrity control, and etc.)

A specialist should collect all tests, needed for the each of the above-mentioned types of testing execution, and assure that a certain full tests list is created for each system feature. Nothing should be neglected by a tester.

Such principle of the total control ensures enough test coverage fullness. Thus, the product quality will be high and a system will operate without failures and errors.
