Senior QA / SDET

Set quality strategy for a whole product: get a flaky suite trusted again, stop a second framework creeping in, move testing down the pyramid, give leadership measures that cannot be gamed, and write a release gate people will not route round.

What you'll build

Real portfolio pieces built during the course, not a certificate for its own sake. Each one is work you can show.

  • Flaky test quarantine policyA policy that makes a red pipeline mean something again: how an unreliable test enters quarantine, who owns it, the deadline to fix or remove it, how its results stay visible, and why retries are not the answer.
  • Test strategy noteA product-wide note moving business-rule checks down the pyramid: which checks move to which layer and why, who writes them, what stays end to end, how the payments boundary is protected, and what happens to the pipeline.
  • Quality scorecardThe measures that replace coverage and bugs found in leadership reporting: each defined in DORA's own words or as a clear outcome, why it resists gaming, how it is shown, and what it will never be used for.
  • Release gate policyThe written rule for what blocks a release: the critical paths and the tests that guard them, what does not block, the named override route with its record, and the review that turns overrides into improvements.

Description

Every CertClue course follows the same seven-part shape: fundamentals, the role translated out of job-posting language, a real working day, the job's recurring rhythms, a multi-day simulation, the portfolio you build along the way, and a handoff into your next move. Here is what that looks like for senior qa / sdet.
