How can we accelerate test cycles? This is a question that both large companies and small businesses alike ask. It is just as essential to evaluate a system and its components to determine if they meet the requirements of the end users.

Organizations strive to improve speed and quality while shipping new products or features. This is why automation in Agile has been vital to speeding up go-to-market without sacrificing quality metrics. Automation alone will not give you the necessary boost to improve your test velocity.

This post will help you as a guide to speed up your jest tests. 

Steps To Speed Up Your Jest Tests In 2023

1.Leverage Your Database Calls

Most automated tests generate test data via browsers. This is a waste of time. Instead, you can create data directly in the databases. Database calls are efficient in terms of time and cost. The test is more reliable if the interface interaction is minimized.

This approach is only beneficial if there is a complex database interaction. When performing database testing, you need to be careful. If you approach it correctly, it can make your life much easier.

2.Strategize Cross-Browser Testing

Cross-browser testing has a wide range of applications. There are hundreds of OS and browser combinations you can test on, and many new devices and browser updates are being released every month. To ensure that the browsers and devices you test on are compatible, you must create a cross-browser testing strategy.

You can avoid cross-browser compatibility issues by prioritizing the most crucial browser and OS combinations. This will allow you to save time and not compromise the quality of cross-browser compatibility tests throughout the testing cycle.

Cloud Testing Platforms such as LambdaTest provide an online Browser Farm with 3000+ browsers and operating systems to conduct cross-browser testing at scale.

3.CI/CD Build Execution Should Be Well Optimized

It is time to change your testing strategy if you spend too much time waiting for an upgrade or a build to be released. You can save time by using a special CI/CD tool instead of the more traditional approach. The scope of the test cases will also determine the amount of time needed. Being specific, concise, and clear about your goals is essential. Automation testing has many benefits, including increasing testing speed. However, automating the wrong things can lead to problems. Automating everything is a waste of time.

4.Developers Must Be Familiar With Automating Unit Tests

Unit testing is an essential part of any release cycle. A good unit test will result in fewer bugs reported by the QA team.

Cloud-enabled testing platforms like LambdaTest make it easy to automate testing across 3000+ web browsers and apps.

5.Leverage Parallel Testing

Instead of performing each test sequentially, you can execute multiple test cases simultaneously to make the task easier. Automation allows you to test more of your software quicker.

Parallel testing allows more test cases to be run in a shorter time, which can lead to a faster test cycle. A good strategy for similar testing is to use different browsers to run other threads. Parallel testing can be seamless using the best Selenium Grid Online and cloud-based infrastructure.

6.Follow Modular Approach 

A modular approach to test management allows you to create a complete suite of automated and manual tests that are easier to maintain. These suites can detect defects and make it easier for engineers to analyze them. It is also possible to reuse modular tests. This saves the quality assurance team time and effort spent rewriting them. This approach allows for test organization by function, which gives it a solid foundation for automated testing development.

The tester should only be writing new tests sometimes. Instead, he or she should concentrate on the execution of the tests and detecting defects in the application. You can save time by searching for existing modules and editing them to meet the testing requirements.

7.Make Use Of The Right Parameters 

It is essential to judge your team’s performance using suitable parameters. It will lead to wasted time if the team needs to focus on the right set. To move in the right direction, it is important to clearly define your testing goals.

If the team keeps its eyes on a set of distant targets, mapping your test strategy to business goals can be difficult. The test cycle parameters must be clear, concise, and consistent with the requirements. It is possible to waste a lot of time by overestimating or underestimating the goals.

You can start by performing the exploratory test, which combines your plan and tests, and executes it into a rapid series of simultaneous events. Agile is a good choice because the testing process can begin with design, a review of acceptance criteria, and the theoretical side. This continuous testing method is what makes the exploratory test very effective. This method can cover all important parameters.

8.Communication Is Crucial 

Test engineers must make their team the most valuable asset they have. It is essential that the team shares the same workload. The task will be easier and more efficient if everyone is on the same page about documentation, test automation strategy, and planning.

Slack also allows you to hold G-meet and Huddle calls to let testers and developers connect and discuss the bug. The best way to capture a screenshot of the bug or record a short video about how it thrives during testing is to do this. This can be made more accessible by using the right collaboration tool.

9.Use The Right Testing Tools 

No matter what type of testing you perform, having the right tools will make your job much easier. One of the most essential test skills is efficiently using all tools at your disposal. Investing in the right open-source frameworks and automation tools can make your life easier as a quality assurance professional. Many tools can improve your productivity, quality, client satisfaction, and overall productivity. You can save time by selecting the right tools for your specific application.

Sometimes teams will try to get the best out of old tools when there are better options. A quarterly or monthly audit of the team’s tools for testing might be helpful to team leaders. You can also be a testing team member and keep up-to-date with new tools. It’s easy to lose track of which bug to prioritize based on the severity when you have more test cases for web and mobile app testing scenarios. You will need a reliable testing tool in the LambdaTest cloud platform to keep track of all this (which is mandatory).

10.Automate Regression Testing

Regression Testing ensures that your app’s functionality is intact when you make changes to it. This ensures that no bugs are introduced during your testing period. This is true regardless of whether you make small changes to your product or update it extensively.

It is important to ensure that the new code does not clash with the old code. This will confirm that the original code still works after the code changes. It is possible to automate the code and should be done in all cases. They are often repetitive because they are used to test functionality. Automating them will free up manual testers for more important tasks.

During agile testing, we use frequent build cycles and continuous integration, changes and deployment. Regression testing is an essential part of agile testing if you want continuous feedback. Regression testing should be started by the product development team from the beginning to encourage 100% success. During your test cycle, you should continue to build it with development sprints.

11.Review Your Code

If you want to reduce the number of coding errors, it is always a good idea to review the code reviews. By providing code review training, tracking it, and writing better code review cases, you can improve your code review. To find memory leaks, you can use a variety of tools. You will need to identify the root cause of the bug and analyze the data to determine the scope for improvement.

12.Make Use Of LT Browser For Responsive Testing

LT browser is our testing tool that ensures your website’s responsiveness. It can be tested on many devices and viewports. Simply open a website using the LT Browser platform. Live testing is possible on over 3000+ pre-installed devices viewports. How can you use LT Browser?
