Package bincover provides an easy way to measure code coverage of Golang binaries. See examples/ to see how bincover is used to measure coverage of a simple Go application.
var ( ExitCode = 0 )
func RunTest(f func())
RunTest runs function f (usually main), with arguments specified by the flag "args-file", a file of newline-separated args. When f runs to completion (success or failure), RunTest prints (newline-separated): 1. f's output, 2. startOfMetadataMarker 3. a testMetadata struct 4. endOfMetadataMarker
Otherwise, if an unexpected error is encountered during execution, RunTest panics.
NewCoverageCollector initializes a CoverageCollector with the specified merged coverage filename. CollectCoverage can be set to true to collect coverage, or set to false to skip coverage collection. This is provided in order to enable reuse of CoverageCollector for tests where coverage measurement is not needed.
RunBinary runs the instrumented binary at binPath with env environment variables, executing only the test with mainTestName with the specified args.
TearDown merges the coverage profiles collecting from repeated runs of RunBinary. It must be called at the teardown stage of the test suite, otherwise no merged coverage profile will be created.
