Apex Test Kit

Enables creation of arbitrary many-to-one, one-to-many, and many-to-many relationships with a fluent API, as shown in the sales object graph example generating 200 accounts with nested contacts and opportunities.

Provides keywords like index(), repeat(), and arithmetic operations to generate field values automatically, reducing manual coding for test data setup.

Implements given-when-then patterns with strict mode enforcement, making test stubs cleaner and more maintainable, as demonstrated in the BDD example with ATK.mock().

Mock data generation is significantly faster than database inserts, with benchmarks showing up to 6.5x speed improvement in real time for 1000 accounts.
