Success expectations

    "test string".should.equal("test string");
    "test string".should.not.equal("test");

    /// or using the Assert utility
    Assert.equal("test string", "test string");
    Assert.notEqual("test string", "test");

Failing expectations

     "test string".should.equal("test");
     "test string".should.not.equal("test string");

Contain

Success expectations

    "test string".should.contain(["string", "test"]);
    "test string".should.not.contain(["other", "value"]);

    "test string".should.contain("string");
    "test string".should.not.contain("other");

    "test string".should.contain('s');
    "test string".should.not.contain('z');

    /// or using the Assert utility
    Assert.contain("test string", ["string", "test"]);
    Assert.notContain("test string", ["other", "value"]);

    Assert.contain("test string", "test");
    Assert.notContain("test string", "other");

    Assert.contain("test string", 't');
    Assert.notContain("test string", 'z');

Failing expectations

    "test string".should.contain(["other", "message"]);
    "test string".should.contain("other");
    "test string".should.contain('o');
