Login Application Manual Exercise

In today’s digital world, test engineers must have effective and efficient strategies and skills to test software in fast-paced agile environments. The Postman tool for API testing is a well-known tool to build, test, and publish APIs, as it allows you to execute ad hoc testing and fully automated test suites. WebdriverIO is a modern JavaScript testing framework for browser and mobile automated testing. 

You will begin with the basics of old and new approaches to building and testing software. Then, you will learn about test planning and design strategies that help a test engineer to select the best approaches to executing test cases for any application. Next, you’ll cover how to test an application using Postman from the end user’s perspective. You’ll finish the course by testing a work order manager with Postman and WebdriverIO.

By the end of this course, you’ll gain essential skills to succeed and advance in a career in test engineering or other roles applying testing activities.

Testing React Applications with Postman and WebdriverIO

const vowels = (str) => {
  const matches = str.match(/[aeiou]/gi);
  return matches ? matches.length : 0;
};

Let’s explain the code written in the example above:

* In **line 1**, we have a `vowels` function that takes in one parameter, `str`, which is a word passed into the function as a JavaScript `string` to test. 

* In **line 2**, we use a regular expression to find all the matches of vowels in the string (i.e., `/aeiou/gi`). The `g` flag means that we want to get all matches versus the first match, and the  `i` flag means that we want to ignore the case (i.e., "A" or "a" should be counted as one match). 

* In **line 3**, we return the number of matches found. If no matches are found, we return `0`.

Our goal is to write a unit test to verify the function's behavior. 

Challenge yourself by checking how many vowels are there in a word.
