    Code complexity measures how difficult software is to understand, maintain, and test – not just by length, but by logic depth, structural coupling and branching. The four main types are structural, cognitive, cyclomatic, and essential complexity. Cyclomatic complexity directly drives testing effort: more independent execution paths mean more test cases required to achieve coverage. Keploy…

    API mocking is the practice of simulating an API’s responses with a stand-in service so teams can develop and test without the real backend. Mocks return predefined or recorded responses, enabling parallel development, testing of edge cases and failures, and faster, more reliable test runs when dependencies are unavailable or costly. APIs are most commonly…
