Sometimes, the software creators have limitations in budget and time for the product release on the market, but, nevertheless, they are aware that the system should always be tested for compliance with quality requirements otherwise it can lead to large losses.

For such situations, when to perform a full range of software testing services is impossible because of some specific circumstances, a minimum package consisting of smoke testing and regression testing is usually offered.

Smoke testing is a bit like the functional testing because of the uniformity of their targets. This is a short cycle of tests, which is performed to confirm that after the build of code (new or updated) the software runs properly and performs basic functions.

Regression testing is aimed at verification changes after detection and fixing bugs in the application or the environment to ensure that pre-existing functionality works as before and has no unexpected adverse effects.

Common Features of the Smoke Testing and Regression Testing:

Both of these testing types may be performed with the involvement of the manual testing elements and automated testing.
Smoke testing does not require great financial and time costs due to the fact that checks are carried out only for basic functionality without details. Regression testing is also economical, because it simply rechecks the bugs fixed in the system.
Smoke testing and regression testing are performed using scripts.

Thus, any software should be tested before the release, and even if the resources are rather limited, the customer can always use a set consisting of smoke testing and regression testing to ensure that the basic functions of the system were tested and bugs were corrected.
