What is Automated UI Testing?
The user interface enables users to interact with your software. It includes all the visual elements like forms, buttons, menus etc. that accept inputs and display outputs.
Testing the UI is vital to ensure a seamless user experience. So what exactly comprises UI testing?
- Checking navigation flows
- Validating data workflows
- Testing all inputs and buttons
- Examining error handling
- Assessing responsiveness across devices
- Evaluating visual appeal
Performing such exhaustive manual UI testing with each software update is extremely tedious.
This is where automated UI testing comes in – to eliminate repetitive human effort through test automation.
Here‘s how automated UI testing works:
Special test automation tools are used to create scripts that simulate user interactions with the UI. These scripts automate various manual test workflows across the interface.
For example, an automated test script can:
- Load your web page
- Enter data into a specific field, say a login form
- Click the submit button
- Validate if the resulting home page loaded has the expected elements
Such scripts continuously run to test UI functionality throughout your development cycle. They fill forms, click buttons, enter erroneous inputs etc. to validate that your UI works flawlessly under different test cases.
In essence, automated UI testing allows simulating real user interactions to identify UI defects before your customers do!
Why Do You Need Automated UI Testing?
Let’s look at some key metrics that showcase why test automation is invaluable:
- A Delphix survey revealed that teams deploy 46x more frequently when practicing test automation
- 72% of teams practicing test automation release applications at least once a week or daily
Frequent releases allow us to delight customers with continuous delivery of value. Other benefits include:
1. Boost release velocity
Automated testing accelerates repetitive test executions, freeing up precious engineering time. This empowers your team to release software faster.
You gain the speed needed to keep up with the demands of the competitive software landscape!
2. Improve test coverage
Studies show that teams increase test coverage by 50 to 100% by adopting test automation. Wider coverage allows discovering defects much earlier.
3. Enhance software quality
Higher test coverage directly translates to better quality! 80% of bugs are found with 20% test coverage. Expanding coverage further helps detect intricate defects beyond the obvious ones.
4. Maximize test accuracy
Automated tests perform precisely the same steps consistently without human errors creeping in. This improves accuracy of your test suites.
5. Optimize costs
Although there is some initial investment required to build automated test suites, rigorous automation reduces testing costs by 40% to 80% as per credible industry analysis.
Clearly, test automation turbocharges teams to achieve phenomenal outcomes!
Now that I have convinced you about its importance, let me introduce you to popular test automation tools.
