go-binmock

A library to mock interactions with collaborating executables. It works by creating a fake executable that can be orchestrated by the test. The path of the test executable can be injected into the system under test.

Usage

Creating a mock binary and getting its path:

Monit = binmock.NewBinMock(ginkgo.Fail)
tPath := mockMonit.Path

gToTest := NewThingToTest(monitPath)

Setting up expected interactions with the binary:

Monit.WhenCalledWith("start", "all").WillExitWith(0)
Monit.WhenCalledWith("summary").WillPrintToStdOut(output)
Monit.WhenCalledWith("summary").WillPrintToStdOut(output).WillPrintToStdErr("Noooo!").WillExitWith(1)

Asserting on the interactions with the binary, after the fact:

ct(mockPGDump.Invocations()).To(HaveLen(1))
ct(mockPGDump.Invocations()[0].Args()).To(Equal([]string{"dbname"}))
ct(mockPGDump.Invocations()[0].Env()).To(HaveKeyWithValue("PGPASS", "p@ssw0rd"))

For a working example you can look at backup-and-restore-sdk
