+# goleak [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Goroutine leak detector to help avoid Goroutine leaks.
+
+## Installation
+
+You can use `go get` to get the latest version:
+
+`go get -u go.uber.org/goleak`
+
+`goleak` also supports semver releases. It is compatible with Go 1.5+.
+
+## Quick Start
+
+To verify that there are no unexpected goroutines running at the end of a test:
+
+```go
+func TestA(t *testing.T) {
+	defer goleak.VerifyNone(t)
+
+	// test logic here.
+}
+```
+
+Instead of checking for leaks at the end of every test, `goleak` can also be run
+at the end of every test package by creating a `TestMain` function for your
+package:
+
+```go
+func TestMain(m *testing.M) {
+	goleak.VerifyTestMain(m)
+}
+```
+
+## Determine Source of Package Leaks
+
+When verifying leaks using `TestMain`, the leak test is only run once after all tests
+have been run. This is typically enough to ensure there's no goroutines leaked from
+tests, but when there are leaks, it's hard to determine which test is causing them.
+
+You can use the following bash script to determine the source of the failing test:
+
+```sh
+# Create a test binary which will be used to run each test individually
+$ go test -c -o tests
+
+# Run each test individually, printing "." for successful tests, or the test name
+# for failing tests.
+$ for test in $(go test -list . | grep -E "^(Test|Example)"); do ./tests -test.run "^$test\$" &>/dev/null && echo -n "." || echo "\n$test failed"; done
+```
+
+This will only print names of failing tests which can be investigated individually. E.g.,
+
+```
+.....
+TestLeakyTest failed
+.......
+```
+
+## Stability
+
+goleak is v1 and follows [SemVer](http://semver.org/) strictly.
+
+No breaking changes will be made to exported APIs before 2.0.
