Attach Screenshots on Test Failure — WebdriverIO

Table of Content

Wouldn’t it be nice to know the exact state of the application you are testing whenever a test failed to help debug your tests? Well, with WebdriverIO, you can easily take screenshots of the application on test failure and can attach it with your reporter.

Let’s take a look at how we can do that with Allure reporter –

Prerequisite

Need to have Allure reporting setup already with your tests. You can watch this video to see how to do that.

Setup

You’ll need to edit the afterTest hook in the wdio.conf.js file

afterTest: function (
    test,
    context,
    { error, result, duration, passed, retries }
  ) {
    // take a screenshot anytime a test fails and throws an error
    if (error) {
      browser.takeScreenshot();
    }
  },

Now just run your tests normally and when a test will fail you’ll see an attachment in your Allure report ? –

Understanding Equivalence Partitioning and Boundary Value Analysis in Software Testing

Software testing techniques help ensure software quality and reliability, by helping us select test cases intelligently from the collection of test cases, such that all test scenarios are covered.

Boundary Value Analysis and Equivalence Partitioning are two testing techniques that help testers select a subset of test cases that covers all important test scenarios, even under time and budget constraints. By testing all the equivalence classes and boundary values, testers can reduce the risk of releasing software with defects.
