There are multiple types of automated testing tools, web automation, desktop automation, API testing. It is vital that the benefits and constraints of tooling is understood so that the right decision can be made during the selection process.
The most commonly used form of automated testing is web automation. The purpose of web automation is to interact with a web page in the same manor as a user would, in order to test user scenarios quickly and consecutively. It is important when choosing an automation framework to ensure it can complete the steps in your test cases. Some of the most commonly used frameworks and tools are:
This web driver allows cross-browser interaction with the elements on a page and can do most of the tasks a user can do, it is the most used framework due to it being open source and very simple to set up and use. Although it does have slight issues with certain steps, where it can fail for no reason on random runs.
Here are some wrappers built upon Selenium WebDriver:
This tool is an testing solution that builds upon selenium, giving it a visual way of designing and developing test scripts. It is extremely easy to use and beginners are able to pick this up without any coding knowledge. The draw back is that it can be quite heavy to use as it will take more resources to run than selenium. This can mean that larger test suites will become a struggle as they expand.
The solution is free, but has a licensed option with more features.
This is a Microsoft product developed by the team who created Puppeteer. Intended to be an alternative to Selenium, Playwright helps to overcome some of the instability issues within Selenium. Playwright is a web driver that allows cross-browser interaction with elements within the browser. It is in it’s early stages at the moment but shows great potential.
Choosing the right tool is one of the most important steps of developing a framework and integrating it into your workflow. Choosing a tool that doesn’t offer the right functionality for you could result in massive technical debt right at the start, and eventually costing the business money.
It is important to identify the business needs for an automation tool as early as possible, identify early adopters of the tooling by finding skill within your test teams, and produce proof of concepts for tools before implementing them.
