QUESTION
I'm a beginner with Cypress and JavaScript. I'm trying to improve the following assertion, I report it below.
Here:
...ANSWER
Answered 2022-Mar-23 at 22:32What you need to shorten the url assertion is a partial string check, since house.js is part of url("https://assets.website.com/folder/house.jpg").
Cypress commands pass along a "subject" from one step to the next. So cy.xpath('//div[@data-testid="column"]') passes the whole element to .should().
You can change the subject from the element to it's background-image style value using the jQuery css() method.
QUESTION
So I want to create an assertion class like how AssertJ works. I'm having trouble getting started.
...ANSWER
Answered 2022-Mar-22 at 18:21I don't think that's how JUnit works (but AssertJ does).
But yes, you create an instance with a static method and hold the value, and then perform an assertion against that value.
New invocations to the static method (also know as factory method) will create different instances.
Here's a very simple example:

QUESTION
TypeScript has is operator which helps to create a test function for type checking. Recently I saw two different implementations of this operator, one of which uses asserts keyword.
I didn't find information about the difference of the two ways of use in the docs. I played with it a little and if I'm correct, asserts doesn't let you return anything from the function, but other than this I didn't find any differences.
Here is the code I tested with:
...ANSWER
Answered 2022-Jan-31 at 19:17Summary: The main difference is that one throws while the other has to be used in a conditional.
The functions which potentially throw an exception and return void are called assertion functions.
These make an assertion (you might think of it as creating a contract with the compiler), that if the function doesn't throw an exception, the predicate in the return value will be true. From that point onward (within the current scope), the type information in the predicate will be in effect.
The functions which return boolean values are called type predicates.
Instead of potentially throwing an exception (and causing your program to come to stop unless it's caught (see try...catch), these simply return a boolean value. If the boolean is true, then for the remainder of the scope where the predicate was invoked (e.g. a block of code), the predicate will be in effect.
The documentation links have several examples for each case (and additional information). Here's a demo:

I'm following ex47 in Learn Python the Hardway by Zed Shaw, however, in the book he is using outdated software (Nose). I've converted his code/my code to pytest but I'm having some issues.
...ANSWER
Answered 2021-Dec-19 at 19:43Using assert with the comma is telling the assert statement to make multiple assertions. For example assert 1==1, 2==2.
In the case of assert gold.name, "GoldRoom" you're asking python to assert that gold.name and "GoldRoom" are non-empty-which they are. It's not actually testing equality between them.
For example try
