test▌

Writes failing tests first, establishing a strict implementation contract for test-driven development. \n \n Completes the RED phase of TDD by authoring behavior-focused tests that fail for the right reason, then hands off to implementation agents with objective pass criteria \n Delegates test authoring to a tdd_test_writer subagent when available, ensuring tests remain unmodified during implementation \n Detects existing test frameworks and conventions (pytest, jest, vitest, go test, cargo test

Comprehensive guide for writing and running Terraform tests with assertions, mocking, and module validation. \n \n Write test files using .tftest.hcl syntax with run blocks that execute in plan or apply mode, supporting sequential and parallel execution with optional state isolation \n Assert conditions on resource attributes, outputs, and data sources; use expect_failures to validate that invalid inputs are properly rejected \n Mock providers (Terraform 1.7.0+) simulate infrastructure behavior

Unit testing Jakarta Bean Validation constraints and custom validators without Spring context. \n \n Covers testing built-in constraints ( @NotNull , @Email , @Min , @Max , @Size ) and custom @Constraint implementations with violation assertion patterns \n Includes cross-field validation, validation groups for conditional rules, and parameterized test scenarios for multiple inputs \n Provides setup patterns using Validation.buildDefaultValidatorFactory().getValidator() and assertion helpers to e

Expert guidance for designing statistically valid A/B tests and experiments. \n \n Provides a structured hypothesis framework, sample size calculations, and metrics selection (primary, secondary, guardrail) to ensure rigorous test design \n Covers test types (A/B, A/B/n, MVT, split URL), traffic allocation strategies, and implementation approaches (client-side vs. server-side) \n Includes pre-launch checklists, guidance on avoiding common pitfalls like early peeking, and frameworks for analyzing

Systematically identify and fix all failing tests using smart grouping strategies.

Generate comprehensive test plans, test cases, regression suites, and bug reports with Figma design validation. \n \n Create structured test plans with scope, strategy, entry/exit criteria, risk assessment, and timelines \n Generate manual test cases with step-by-step instructions, expected results, preconditions, and priority levels \n Build regression test suites (smoke, targeted, full) with execution order and pass/fail criteria \n Validate UI implementations against Figma designs with compon
