Test phases in the development cycle of a software product are used to ensure quality, as agreed with the client. A test procedure may be more or less rigorous, and thus the testing effort is more or less expensive depending on the required quality level.
Today, businesses dedicated to the world of software testing are increasing. This is largely due to an awareness of the complexity and criticality of the products. It is therefore important that these phases are well integrated in the development cycle based on best practices and streamlining the process.
There are different ways to classify software development solutions tests. There is a classification from three perspectives: the nature of the test object (perspective closely related to the development cycle), the level of knowledge of the structure of the object and the type of characteristic or property (eg, performance).
