Why testing matters
Testing is running a program or algorithm with selected inputs to check whether the outputs match the requirements. Programmers use it to find faults early and to check that valid input is accepted.
Step-by-step lessons covering OCR GCSE Computer Science Testing for GCSE Computer Science. Each lesson works through exam-style questions in Component 01 and Component 02 format. Build strong foundations in binary, logic and core programming constructs before moving on to the more complex algorithm design and evaluation questions.
