A VS Code extension (also compatible with Cursor) that adds support for running individual test cases in Go's table-driven tests.
Features
CodeLens Integration: Adds "Run" and "Debug" buttons above each table test case
Individual Test Execution: Run or debug specific test cases from table-driven tests
Automatic Detection: Automatically detects table-driven test patterns in your Go test files
Go flags and tags support: Support for Go flags and tags to configure the test run
Usage
The extension recognizes common table-driven test patterns:
func TestExample(t *testing.T) {
tests := []struct {
name string
// other fields...
}{
{name: "test case 1"},
{name: "test case 2"},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
// test code
})
}
}
Supported Test Patterns
Note that the variable name must be called tests, testCases, testItems, testWhatevers etc. (in another words, it must contain the word "test" and end with "s"). This is done to avoid false positives on plain struct declarations.
