stub.sh

A set of stubbing helpers for use in bash script tests. Supports stubbing and restoring both binaries and bash functions.

Particularly useful when used in combination with the simple and elegant assert.sh test framework.

Usage

Put stub.sh in your project, source it into your tests. For detailed examples, why not have a look at the tests for stub.sh itself?

Examples

Stubbing binaries:

source "stub.sh"
uname #=> Darwin
stub uname
uname #=> uname stub:
uname -r #=> uname stub: -r
restore uname
uname #=> Darwin

Stubbing bash functions:

source "stub.sh"
my-name-is() { echo "My name is $@."; }
my-name-is Edward #=> Edward
stub my-name-is
my-name-is Edward #=> my-name-is stub: Edward
restore my-name-is
my-name-is Edward #=> Edward
