Common Selenium Mistakes I See (and How to Avoid Them)

Most problems with Selenium happen because of how people use it, not because of Selenium itself.

One mistake I often see is trying to automate every scenario. Not everything needs to be tested through the UI. If you add too many low-value tests to Selenium, your tests can become flaky and harder to maintain, without really improving your coverage.

Another common problem is using weak assertions. If your tests only check that actions succeed but don’t verify the actual results, they might miss real regressions. Good assertions should always confirm the important outcomes.

A poor locator strategy is another issue I see. If you use locators based on styling, position, or content that changes often, your tests can break easily. It’s better to use stable identifiers to make your tests more reliable.

I also notice that some teams ignore failed tests, assuming they’re just flaky. This is risky. You should check every failure until you’re sure it doesn’t matter. Otherwise, people may stop trusting your automation.

Many teams don’t realize how much maintenance automation needs. You can’t just write tests once and forget about them. As your application changes, your tests need to change too. Treat automation as something that grows and changes over time, not as a one-time job.

You don’t need special tools to avoid these mistakes. What matters most is having discipline, a clear purpose, and knowing what you want your automation to achieve.
