FLAKY TESTS

Hello Reader,
I’ve been working on a project to reduce test flakes. A project that has over 1200 end-to-end tests in a fairly complex system. As I’ve been slowly trying to reach zero, a pattern emerged.

It seems like there are common themes when it comes to test flakiness. I shared some of them in my presentation at CypressConf, but lately it seems that flakiness in end-to-end tests is mostly a timing issue. A situation where test and application fall out of sync.

Flaky Tests are like two cars...

Flaky tests make debugging a nightmare and can shake confidence in your test suite. I’ve been looking into the most common causes of flaky tests and how to deal with them.

Test automation tip

Cypress allows you to select only elements that are visible by utilizing :visible pseudo selector from jQuery. This can be quite useful especially when testing submission forms that tend to have hidden input fields.

 1  it(':visible elements', () => {
 2  
 3    const data = ["Filip", "Hric", "90210", "filip@filiphric.sk", "chuckN0rri$"]
 4  
 5    cy.visit('/')
 6  
 7    cy.get('input:visible').each((el, i) => {
 8      cy.wrap(el)
 9        .type(data[i])
10    })
11  
12    cy.contains('button', 'Register')
13      .should('be.enabled')
14  
15  })

Filip Hric 13th May 2025 TO BE OR NOT TO BE (TECHNICAL) Hey Reader!There’s an ongoing debate in the QA world on whether it makes sense to get technical or not. I remember having a fairly heated debate on this last November at Agile Testing Days in Potsdam. My talk titled "Test like a developer, develop like a tester" argued that we should put the effort as testers to become experts in the software we test. And yes, that includes having a fair bit of developer knowledge. Jason Arbon called...
