One of the most important aspects of web site testing, desktop testing and mobile testing is test coverage.

Many people think that test coverage is just a set of similar tests. They believe that it is a homogeneous thing that can be represented in percentage of performed tests, the number of passed and the number of failed tests.

Such approach to test coverage is incorrect and results in poorly executed mobile application testing, desktop testing or web site testing.

In order to test a software product thoroughly one should see it from different perspectives, examine its different aspects. It is necessary to elaborate test-cases for each aspect of the tested program. So, efficient test coverage must consist of test sets checking many various aspects of the system under test.

A software testing company will confirm that the more perspectives of the tested software are included in test coverage, the more careful testing process is. There are quality assurance experts that can use more than a hundred models for test coverage. This fact seems to be unbelievable.

Unfortunately, there is almost always too little time for such detailed examination of a software product. But, anyway, ability to see a program from different angles helps to determine on what aspects it is better to concentrate testing efforts. One can also allocate a little time on many aspects and quickly find the most significant problems in various areas.
