Using Lists to get UI elements with nearly impossible selectors

Where does this approach apply? One of the following:

  • if you have a list of elements with identical selectors. The element you are interested in is an element of that list. But it does not always appear in the same place in the list. Sometimes it might be the third element in the list, other times it might be the second, or the fourth, and so on. You only know that using getText() on the element returns a known text.
  • if the element you are searching for has a different selector each time you open the page. You know only the type of element it is (whether it is a button, or an a element representing a link, or an img element) and what text should be displayed on that element.
  • if the element you are looking for does not even have any attached attributes. That means it is only a tag, without an id or class, or anything else except for the tag name (tag being ‘a’ for links, ‘img’ for images, and so on). You know what getText() should return when applied to that element.

Better Test Code Principles: #4 Keep your production tests separate from your dev environment ones

Automated tests are used to validate features in development environments but also in production. Whereas the classic approach of keeping all tests in the same code project is the most popular, it is not the best idea (and by code project i mean for example a Maven project). Continue reading Better Test Code Principles: #4 Keep your production tests separate from your dev environment ones

Better Test Code Principles: #3 Use external libraries when available

Most of the testing tasks require some data processing, whether it is working with JSON objects, gathering data from a database, processing Strings, working with date types, and so on. Performing the processing requires some code to be written, apart from the tests themselves. But why write that code yourself, if it already exists in an easily usable external library?

@FindBy, Lists and using them to check for similar UI elements

This is going to be a rather complex post, that will show how to easily check for values of similar UI elements. By similar i mean elements that share some kind of properties: whether they have the same CSS selector, or are part of the same group of elements. Some examples will be shown below. Performing the testing part will imply the use of @FindBy (of Selenium WebDriver) and List (of Java). Read on to get an idea of where this approach can be used, how @FindBy is ideal for such a task, what the basics of working with List are, and what an actual test looks like.

Better Test Code Principles: #2 Don’t generate ALL your test data in @BeforeClass

A considerable amount of tests will need some test data to be generated previous to them running. Some people prefer to put all the data creation for all the tests in a class into the @BeforeClass method, some others prefer to keep the prerequisite data creation inside the tests themselves.

Better Test Code Principles: #1 Don’t copy/paste the code. Reuse it.

When starting to learn Java, one of the first things you are taught is that a class consists of several things, among which are the ‘methods’.  A method is nothing more than grouping of several code lines. Since tests are code, the same principle applies to writing your Java based tests. Especially if you are dealing with duplicate code (code you keep copy/pasting all across your test project).

So what would be the reasons for not wanting to duplicate your code, but instead grouping it into methods: Continue reading Better Test Code Principles: #1 Don’t copy/paste the code. Reuse it.
