Installation

Usage

Add the sinon matcher to hamjest by require the module

const __ = require('hamjest');
// auto extend hamjest
require('hamjest-sinon');
// or
require('hamjest-sinon').extendHamjest(__);

// use matcher from hamjest
__.assertThat(stub, __.wasCalled());

Mock matchers

Mock matchers is an extension to Sinon matchers which supports the Jest Mock as well.

Sinon matchers

Sinon matchers are used for testing function calls. Replace the function with a sinon stub or spy and assert the call of the function by your code with these matchers.

wasCalled(valueOrMatcher)

Assert that a sinon stub was called:

    __.assertThat(stub, __.wasCalled());

Assert that a sinon stub was called a specific amount of times:

    __.assertThat(stub, __.wasCalled(2));

Assert that a sinon stub was called a variable amount of times:

    __.assertThat(stub, __.wasCalled(__.greaterThan(1)));

Assert that a sinon stub was not called:

    __.assertThat(stub, __.wasCalled(0));
    // or
    __.assertThat(stub, __.not(__.wasCalled()));

wasCalledWith(valueOrMatcher)

Assert that a sinon stub was called with empty args:

    __.assertThat(stub, __.wasCalledWith());
    // or 
    __.assertThat(stub, __.wasCalledWith(__.undefined()));

Assert that a sinon stub was called with a specific arg:

    __.assertThat(stub, __.wasCalledWith('something'));

Assert that a sinon stub was called a variable arg:

    __.assertThat(stub, __.wasCalledWith(__.containsString('something')));

Assert that a sinon stub was not called with empty arg:

    __.assertThat(stub, __.not(__.wasCalledWith()));
    // or 
    __.assertThat(stub, __.not(__.wasCalledWith(__.undefined())));

wasCalledInOrder(valueOrMatcher)

Assert that a sinon stub was called in order with specific args:

    __.assertThat(stub, __.wasCalledInOrder('first call with args', 'second call with args'));

Assert that a sinon stub was called in order with variable args:

    __.assertThat(stub, __.wasCalledInOrder(__.containsString('first'), __.containsString('second')));

Assert that a sinon stub was not called:

    __.assertThat(stub, __.wasCalledInOrder());
    // or 
    __.assertThat(stub, __.wasCalled(0));
