Selenium Python Wait Commands

In this post, we will learn about the various wait commands available in Selenium Python using the SeleniumBase framework. Using wait commands when doing browser automation is inevitable. Therefore, it’s important to understand how to use wait commands the right way.

Using “Wait” the Wrong way

Now, this one, in particular, is a pet-peeve of mine. I have seen time and again in many codebases where hard-coded sleeps are used instead of implementing the right wait commands. I am sure you have seen this before as well or a variation of the code below –

# I have no idea why this test is failing, so I will simply throw in a random sleep here of 5 seconds. 

While this one line in a single test won’t do much harm but just imagine when this becomes the “norm” for most of your tests. Soon, you will find your test run time to double, triple, or even quadruple * gulps * due to that 1 harmless line.

Using “Wait” conditionally

Now that we know using hard-coded sleep is a bad practice, what can we do when we still need to use wait in our tests? Well, you would still use wait commands but this time you will wait for a particular condition to complete.

For example, if you need to wait for an element to be visible on the screen so that you can perform your next step, you could do something like this –

        # wait for loading screen to appear

In the sample code above, I am not explicitly telling my test to wait ‘x’ amount of seconds before performing the next step. Rather, I am using a max timeout (6 seconds set in config) for my element to be visible on the screen. This way, my element can appear on the screen in 2 secs or 4 seconds, and then it will move on to the next steps saving you a couple of extra seconds!

Some other wait commands to use

        # check whether the element is not visible

        # wait for a particular text to appear
        self.wait_for_text("$300.00", self.subtotal_text)

You can read about all the available wait commands in the SeleniumBase API docs here.

Key Differences Between CI/CD and DevOps

Software development is far from a simple journey that involves merely executing code and launching applications. It often presents challenges, as it’s rare to get everything right from the start. Each time you implement new or frequent code changes, you inadvertently introduce potential issues that can be time-consuming to resolve. This complexity necessitates a structured approach to ensure smooth production.
