Overview

Package exectest builds the pdfconcat executable for tests that run it as a child process, and lets the coverage gate (tools/qualitygate coverage) see what those child processes execute.

When the environment variable PDFCONCAT_COVERDIR names a directory, Build compiles with `go build -cover` (instrumenting the packages listed in PDFCONCAT_COVERPKG, default every package of the module) and Command points the child's GOCOVERDIR at that directory. Otherwise the executable is a plain build and nothing changes.

Functions

func Build 

func Build(tb testing.TB, pkg string) string

Build compiles the main package pkg (for example "./cmd/pdfconcat", relative to the module root) once per test process and returns the executable's path.

func Cleanup 

func Cleanup()

Cleanup removes every executable Build produced. Call it from TestMain after m.Run; a test process that does not leaves its temporary directory behind.

func Command 

func Command(ctx context.Context, path string, args ...string) *exec.Cmd

Command returns a command that runs the executable at path. Under the coverage gate the child's coverage data goes to EnvCoverDir.
