BDD / TDD assertion framework for node.js and the browser that can be paired with any testing framework.
ctx.should.do.foo(barFuncThatReturnsSmth) and I'd like this chain to return the return value of barFuncThatReturnsSmth
this._obj in the definition of the method foo, but that didn't work. The object is there, but is not returned directly (it's hidden inside some __flags object)
Anyone interested in an opensource project?
Spec oriented development speeds up programming by generating code based on tests/specs. Tests required will be the same or less specs as a normal developer writes.

let = expect.to.be.Visible("myElementId");
@aeutalt You could add your own matcher method, https://www.chaijs.com/api/plugins/#addmethodctx-name-method
But I suspect there is some assertion library that someone has made for working with elements already that you could install
it('if test case', async function () {
var cardProcZero = await driver.hasElementByAccessibilityId("card_proc_0"); // looks up the element
var visivel = expect(cardProcZero).to.exist; // expects it to exist
if (cardProcZero == visivel) { // if it is visible, it clicks on it
it('test case 1', async function () {
await cardProcZero.click();
return true;
});
} else {
it('test case 2', async function () { // if it's not visible, it creates the element
let adicionarProc = await driver.waitForElementByAccessibilityId("button_addProcedimento");
await adicionarProc.click();
return false;
})
}
});});

Hi
Is there a way to do soft assertions
Hi Dev! Assuming that "soft assertions" means assertions that when fail, they are logged, but don't stop the test.
Chai, and most other assertion libs, work by throwing an exception whenever an assertion fails. This means you can catch that exception and treat it yourself:
const softAssert = fn => {
try {
fn()
return null
} catch (e) {
return e
}
}
it('should work', () => {
const error = softAssert(() => expect(actual).to.equal(expected))
const error2 = softAssert(() => ...)
...
})However! Take into account that having to do this is a signal that your code may be reliying in exceptions to do normal work, which can lead to convoluted flows. It is better if your code is made to handle error cases with different returned types, instead of exceptions that may or may not be captured at different levels in the architecture.

{ array: [ { element1: Mario, element2: White }, { element1: Luigi, element2: Green } ] } I want to check that the element of array which has element1 equal to Mario has element2 equal to White

expect(1).to.equal(1);
Here's how assertions work:
A test is just a smart try-catch block. If an exception occurs inside, the test fails. Assertions are just functions that throw well formatted exceptions.
If you needed to know if an assertion works, you can wrap it in a try-catch yourself, and re-throw it in the catch:
try {
expect(1).to.equal(2)
} catch (failedAssertion) {
console.log(failedAssertion)
throw failedAssertion
}
Is it possible to test if array contians objects that are superset of target objects. For examle, I'd like following to pass:
var value_under_test = [ {id: 5, name: "N1"}, {id:6, name: "N2"}]
var assertion_value = [{id:5}, {id: 6}]
expect(value_under_test).to. have.????.(assertion_value)I know I can first map value_under_test and then to.have.deep.members but that can get ugly if I have to pick more than one key
