Software testing is an investigation process conducted to obtain information on the quality of the product under test. Today’s types of software testing are not sufficient enough to help completely identify all the defects and verify whether the system being tested performs correctly. Therefore, all the types of testing available are used for formal verification of software that is being developed or tested.

Software testing services are necessary to improve quality & performance of IT application; they range from custom verification to specialized testing. This formal validation or verification process can prove the absence of defects in the terms of the method used. Thus, there is no way to track all bugs so that to expect zero defects in the software product, taking into account “human factor ”that relates to all phases of the software life cycle.

There are many approaches to solving the problem of software testing, but efficient testing of complex software products is essentially a very creative process that does not require strict adherence to the policies and the standard operating procedures.

According to the ISO 9126, the software quality can be defined as the totality of characteristics of software under test, considering the following components:

  • Reliability.
  • Maintainability.
  • Practicability.
  • Effectiveness.
  • Mobility.
  • Functionality.

QA testing services are helpful in saving on time and effort in testing, enhancing its efficiency and precision while cutting costs and risks.

The History of Software Testing

Software systems were first developed under research programs or Defense Department programs. In the 1960s, much attention was paid to “exhaustive” testing, which was to be performed using all code paths, or all possible entries.
In the early 1970s, software testing was referred to as “process conducted to prove the correctness properties of software product” or an activity intended to ensure that the software works as it is expected to. In the 1980s, a definition of testing was expanded to defect prevention as well as bug detection activities. Designing tests is the most effective of well- known error-prevention techniques.

In the early 1990s, a definition of “testing” was expanded to include planning, design, development, support, execution of tests and creation of test environments, and this marked a transition from testing processes to quality assurance services, covering the entire software development lifecycle.
