Implicit Assertions Are More Readable (opens on the source site)
Cypress can test the current subject using implicit assertions that I find more readable than the explicit Chai assertions. Recently I saw a Linkedin post that shows "before & after" API test using Cypress. Here is the screenshot included in the post. Right away, I want to say that the "after" test is better. It checks the response status first, then confirms the types and ranges of values, rather than hard codes the new item's id and creation date. The "after" test will probably pass, while the first test will probably fail really quickly on new runs. I like the general idea. But I think…

Has It Not Happened Yet (opens on the source site)
Do not confuse negative assertion with a quick timeout. Let me get back to the testing of negative states one more time. Recently, I have read a pretty good blog post How to test that cache works with Cypress by Walmyr. A piece of Cypress test syntax caught my eye: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 cy.search(randomWord).then(() => { expect(count, `network calls to fetch ${randomWord}`).to.equal( 1, ) cy.wait('@random') cy.search(randomWord).then(() => { expect( count, `network calls to fetch ${randomWord}`, ).to.equal(1) }) }) The test above confirms that the web page caches the search…
