How it works currently is: This means that expect(1).toEqual(2, 'because of stuff') ends up printing out: Presumably though, real code would look something more like: In this case, jasmine would encourage you to instead write a custom matcher so you would have something like: And then the custom matcher can specify any failure message you want. The syntax is as follows: jasmine.createSpyObj(baseName, methodNames) baseName. It is used in BDD (behavior-driven development) programming which focuses more on the business value than on the technical details. Is there a topology on the reals such that the continuous functions of that topology are precisely the differentiable functions? So I did it for my own for jasmine 2.0 and the related definitely-typed and I've posted it here: https://github.com/davidemannone/jasmine2.0-explained To create a spy on any method, use spyOn(object, 'methodName') call.

I do hear the need for some way to tell Jasmine some sort of description of the value being checked, but I don't think it will be as an additional argument to the matcher itself.

In case, you do not want to disable whole suite and rather want to disable only a certain spec test, then put the x before that spec itself and this time only this spec will be skipped. toHaveBeenCalled matcher will return true if the spy was called; and toHaveBeenCalledWith matcher will return true if the argument list matches any of the recorded calls to the spy. In case of nested describe, before executing a spec, Jasmine walks down executing each beforeEach function in order, then executes the spec, and lastly walks up executing each afterEach function.

Unfortunately this is a hack, it doesn't work with all matchers, and the .because syntax would be so much cleaner. So you would have something like (beware, untested code): Both of which jasmine could turn into a nice message, or you could have the custom matcher itself provide you with whatever message you want. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); document.getElementById( "ak_js_2" ).setAttribute( "value", ( new Date() ).getTime() ); HowToDoInJava provides tutorials and how-to guides on Java and related technologies. Since that one cannot be annotated, I suggest passing a regular old-style function to the outermost describe: Thanks for contributing an answer to Stack Overflow! @slackersoft any chance this is still on the radar of the project? Lets understand it by an example. Mostly, these spies are used as callback functions to other functions where it is needed. Thanks for contributing an answer to Stack Overflow! I know pivotal has not included this feature in the past on the assumption that it allows poor test code, but it seems to me that they either need to include a feature like TestCase from nunit, or add this 'because' feature. First download jasmine framework and extract it inside your project folder. Already on GitHub? .toBe(expected, output) seems to work OK, however .toEqual(expected, output) does not. It's not documented behavior, and so could change, so I wouldn't rely on it. Non-anthropic, universal units of time for active SETI.

Well occasionally send you account related emails. But there is no implementation behind it. The current folder structure is below: To concentrate on what Jasmine is capable of, I am creating a simple JS file MathUtils.js with some basic operations and we will unit-test these functions. Everything you do in order to get this level of reusability with Jasmine will be a workaround, not designed by the creators. @james I've taken a small look at sinonwould that allow me to use contexts? Jasmine is very capable framework for testing javascript functions, but learning curve is little bit difficult. Itis painful to search for the actual cause when a scenario fails and we have to check all assertions. for mathematical comparisons of less than, for mathematical comparisons of greater than, for testing if a function throws an exception. In your demo code, when you call $controller function inside the first beforeEach it will resolve all its dependencies using the default value no matter what you do. createSpyObj () The createSpyObj () creates a mock object with multiple spies.

If you need to define multiple such methods then you can use shortcut method jasmine.createSpyObj. Thanks a lotclientside testing is a nightmare compared to serverside! The problem is that TypeScript is not smart enough to figure out that this inside beforeEach is exactly the same this as in it. In this Jasmine tutorial, we will learn Jasmine framework in detail from setup instructions to understanding output of testcases. The afterEach function is called once after each spec.

Writing a custom matcher for the sole purpose of more descriptive messages doesn't seem like a brilliant idea, and, more to the point, every time you want a custom message, especially when a more general solution has been proposed. @jfrioux unfortunately I'm not willing to commit my entire company's code base to an undocumented feature than could be removed at any time (and as noted above, doesn't seem to work for me anyways).
