Software Testing Services Companies: Difference Between Static and Dynamic Testing Types
Static software testing
Static testing involves careful examination of the program code to verify the compliance with code practices without executing the code itself. It can be done either manually or automatically. Static testing techniques are often used by software testing services companies as these play important role in the development life cycle as a whole.
Static analysis tools are graphical processors such as printout programs, crossreference programs, compilers, discrete event simulators, cyclomatic complexity analyzers (counters), static control programs, branch printout programs and others. During static analysis, project-based assessments and some other types of static testing, some of the processes are carried out by hand.
Normally, the testers search for software bugs early in the development process, since they may be introduced in each phase. At that static testing should be run throughout the entire development life cycle but this verification is especially efficient before making an executable file.
Be advised that top software testing companies use the best grammar & spell checkers that help not only find and correct grammatical & spelling mistakes, plagiarism, vocabulary issues in associated documents, but also search for text strings that are not found in the dictionary and replace them with the close-spelling words.
Dynamic software testing
This testing is conducted in the final phases of software development life cycle. In dynamic analysis, the tester examines the dynamic behavior of the program’s code by executing it on computer. The process involves giving input and exploring output. It is performed in Validation process.
In dynamic testing such factors as fault-free hardware, correctly installed & configured operating system, compilers, etc. are to be taken into account. Any of these may introduce software bugs which are found during testing.
Some software programs are designed to work in a multiuser environment; it is when multiuser databases are simultaneously accessible from many computers. To test multi-user application, you need a well-defined test plan and proper installation and configuration of data terminals, file framework, data links and a cohesive testing team.
To ensure high performance of software programs many businesses use services of load testing companies. Load tests help to identify and remove performance bottlenecks in the apps until the programs meet their performance goals.
