mock-nodemailer

A small framework to mock out nodemailer in your tests.

Usage

test('email gets sent', function(done) {

    var email = {
        to: Faker.Internet.email(),
        text: Faker.Lorem.sentence(),
        subject: Faker.Lorem.sentence()
    };

    mockMailer.mock(email, done);

    transport.sendMail(email, function() {});

});

test('email gets sent, throwing if an email is not ours', function(done) {

    var email = {
        to: Faker.Internet.email(),
        text: Faker.Lorem.sentence(),
        subject: Faker.Lorem.sentence()
    };

    mockMailer.mock(function(sentEmail) {
        assert.deepEqual(email, sentEmail);
        return true;
    }, done);

    transport.sendMail(email, function() {});

});

test('email gets sent, returning falsy if an email is not ours', function(done) {

    var email = {
        to: Faker.Internet.email(),
        text: Faker.Lorem.sentence(),
        subject: Faker.Lorem.sentence()
    };

    mockMailer.mock(function(sentEmail) {
        return _.isEqual(email, sentEmail);
    }, done);

    transport.sendMail(email, function() {});

});

test('multiple emails get sent', function(done) {

    var email = {
        to: Faker.Internet.email(),
        text: Faker.Lorem.sentence(),
        subject: Faker.Lorem.sentence()
    };

    mockMailer.mock(5, function(sentEmail) {
        return _.isEqual(email, sentEmail);
    }, done);

    _.times(5, function() {
        transport.sendMail(email, function() {});
    });

});
