2.1.2. Software Development Lifecycle and Good Testing Practices
Good testing practices, independent of the chosen SDLC model, include the following:
• For every software development activity, there is a corresponding test activity, so that all
development activities are subject to quality control
• Different test levels (see chapter 2.2.1) have specific and different test objectives, which allows
for testing to be appropriately comprehensive while avoiding redundancy
• Test analysis and design for a given test level begins during the corresponding development
phase of the SDLC, so that testing can adhere to the principle of early testing (see section 1.3)
• Testers are involved in reviewing work products as soon as drafts of this documentation are
available, so that this earlier testing and defect detection can support the shift-left strategy (see
section 2.1.5)
