How is shift-left testing distinct from old accessibility testing?
Shift-left testing highlights integrating test actions as well as accessibility considerations earlier in the SDLC, preferably along with coding, while an outdated form of testing is often done at the end of development. This variance in approach & timing results in multiple key distinctions. Let us find out a breakdown of the differences:
1. Timing
- Traditional
Accessibility testing is sometimes executed as a separate stage after a product has been released or at the end of development.
- Shift-left
Accessibility testing is incorporated into the SDLC from the beginning. This encompasses actions such as using automated accessibility checks while coding, including accessibility guidelines into design, and accessibility specialists early in the SDLC.
2. Error Detection
- Traditional
Accessibility problems are often discovered in the late phase of the SDLC or after launch, resulting in more significant revision & potential delays.
- Shift-left
By testing often & early, potential accessibility problems are detected & addressed while they are simpler & smaller to address. This results in fewer late-phase errors & a smoother development procedure.
3. Partnership
- Traditional
Accessibility testing is sometimes treated as an individual task, potentially resulting in a siloed system & less partnership.
- Shift-left
Shift-left testing increases teamwork between accessibility experts from the outset and developers, testers, and designers producing a communicative & integrated environ.
4. Effort & Cost
- Traditional
Reworking accessibility problems later in the SDLC can be time-consuming & expensive, particularly if important changes are needed.
- Shift-left
Finding accessibility issues in the early stage can considerably decrease the effort & expense related to fixing them later. Fixing problems during the early development or design phase is much more effective than addressing them after the product is built.
5. Focus
