Control Flow
4.1🔒OverviewControl flow decides which code runs and how often. Every test relies on conditions to verify results and loops to iterate over data sets…
4.2🔒If / ElseThe most fundamental control structure. In QA, you use it to branch on status codes, validate fields, and classify test outcomes.
4.3🔒Match / SwitchWhen you compare a single value against many discrete options, match/switch is cleaner than chained if/else.
4.4🔒For and While LoopsLoops let you iterate over test data, retry flaky operations, and process collections of results.
4.5🔒Comprehensions and Functional IterationPython has list comprehensions. JavaScript and TypeScript use .map(), .filter(), and .reduce().
4.6🔒Exercises: Chapter 4Easy: Write a function in all three languages that takes a list of HTTP status codes and returns an object/dict with counts grouped by…
4.7🔒Q&AQuiz: Chapter 41. What keyword does Python use instead of else if? 2. In TypeScript, why is an enum with a switch statement safer than using raw strings?…
4.8🔒Career Translation- Implemented conditional test logic for status code classification, environment-specific test execution, and dynamic test skipping based…
4.9🔒Q&AInterview Depth CheckPrompt: How would you implement a retry mechanism for a flaky API call that sometimes times out, without masking real failures? What a…
