name: go-testing description: Go testing patterns. Routes to specific patterns.

Testing

Route by Pattern

• Table-driven tests → see table/
• Subtests with t.Run → see subtests/
• Test helpers → see helpers/
• Benchmarks → see benchmarks/

Quick Check

• Tests named Test_Function_Scenario
• Table tests for >2 cases
• Helpers call t.Helper()
• Parallel tests capture loop vars

Common Patterns

Basic test structure:

Copyfunc Test_Function_Scenario(t *testing.T) {
    // Arrange
    input := "test"

    // Act
    result := Function(input)

    // Assert
    if result != expected {
        t.Errorf("got %v, want %v", result, expected)
    }
}
