What Are The Best Ways To Reduce Test Execution Time?

Time is critical in today’s fast-paced application development environment. Gaining a competitive edge involves releasing new applications with high quality and functionality quickly. Providing a top-notch application alone is insufficient. Executing tests quickly and efficiently has become an essential differentiator. Developers and testers are always under pressure to release often and on schedule.

Because test execution time affects how quickly and thoroughly testers can confirm the operation and performance of their application, it is a crucial component of application quality assurance. However, whenever the source code is updated, both new and old test cases must be run on various platforms and operating system combinations. Manually testing each of these variants is inconsistent, time-consuming, and not cost-effective.

As a result, a lot of developers and testers are figuring out how to expand and optimize their test cycle to accelerate it. As a result, many of them are implementing test automation to guarantee high-quality deliveries.

Test automation can, however, be time-consuming and complicated if done incorrectly. Managing test automation execution time can be difficult, particularly when testers have to deal with complicated systems, various environments, and changing requirements. Therefore, teams must figure out how to shorten test execution times.

We will talk about some of the most significant ways to shorten test execution times in this article. Before moving on to that let’s first quickly review what test execution is, and the reasons why it is crucial to shorten test execution times.

What is test execution?

A series of specifically created test cases are executed on the application to ascertain its functional and non-functional parameters about the requirements. This process is known as test execution. The process of executing tests is guided by a test strategy and test analysis, which breaks down the entire task into distinct requirements and/or modules and provides thorough test cases for each.

Although it seems that running tests is an automatic process, this is not the reality. The test execution phase is surrounded by several stages, and each one requires adjustments, including setup, planning, and preparation.

The first step is to plan, which includes creating the code, designing the script, writing the test script, determining the direction to take, and more. After this is finished, senior team members evaluate the technical portion of the plan before approving it.

Writing the test cases comes next, after which the testers can start running the tests and recording the results to see if the actual results match the desired outcomes. They record any errors or flaws, file a report for them, test the remedies again, and follow the errors through to completion. This is completed on the application that the development team has prepared for client release.

The need for reducing test execution time

The most crucial stage of the application testing life cycle is test execution. It makes sure that issues are found quickly and assesses if the application is prepared for release. The application may need to repeat the development and testing life cycle if the execution results fall short of the anticipated or intended outcomes.

Accurate test results, which include the number of bugs discovered, their severity, and the features or functions affected, depend on efficient test execution. However, scheduling and resource limitations, such as inadequate staffing levels, insufficient test environments, and tight deadlines, can also make test execution difficult.

Timelines for app releases are getting drastically shorter since users have no patience to wait for updates, repairs, or new features. In light of this, developers and testers must efficiently oversee the test execution process to speed up delivery, eliminate errors, and reduce the duration of the release cycle.

Higher productivity in research and development is made possible by a shorter test cycle. Since it involves modeling, experimentation, simulations, and testing, shortening the testing cycle might result in more cycles and higher success rates.

While an application is being developed, developers can enable frequent builds and releases by cutting down on test execution time. By doing so, they can accelerate time-to-market and accomplish result-driven development by testing the builds on real devices. This facilitates immediate integration of the latest developments into widely available applications.

Ways to reduce test execution time

Today’s organizations are more conscious than ever of the need to produce high-quality applications quickly and within the ever-expanding testing scope. Testing takes way too long, which is one of the main reasons why so many of them fail. The likelihood of an unsuccessful outcome increases with the duration of execution. To ensure bug-free, timely application releases, testers, and developers are frequently under pressure to expedite application delivery by reducing test execution time.

In light of this, we have provided a short list of ways that developers and testers can use to shorten test execution durations and increase test efficiency and speed.

Identify and use page elements effectively

Determining the items on the page is one of the most crucial things to take into account while writing code. For the testing to pass, a reliable and efficient method must be used.

Adding distinguishing features to the page’s elements is one tactic. This reduces flakiness and greatly facilitates the code’s ability to locate the components.

Apart from employing distinctive attributes, there are several methods to enhance the locator strategy.

Use standard locators like ID, name, CSS selector, and link text first. Compared to other locators like XPath, these locators are a bit more reliable.

Secondly, do not use locators such as link text. Since the link text is susceptible to change, this could result in several tests failing. Alternatively, the href property or the link’s entire text could be utilized.

Use explicit waits

Using explicit waits instead of implicit ones is another efficient technique to cut down on test execution time. In a test script, implicit waits establish a default wait time between each command or step, ensuring that the next operation only runs once the pre-specified duration of time has passed. Longer run times and flakiness could result from this.

In contrast, explicit waits allow a script’s subsequent step to begin running as soon as the previous one is finished. Using solely explicit waits can lead to a shorter test run time; however, it is more difficult to implement.

Use the cache memory provided by the browser itself

Rather than constantly obtaining data from the data server, store information in a cache within the browser. By doing this, the data will be stored locally and be more quickly accessed.

It is also possible to set the cache’s expiration timings, which will cause it to automatically update as new information becomes available. Caching can help reduce the amount of work that needs to be done and speed up the test suite’s total execution duration. As a result, this may aid in enhancing the effectiveness of web automation tests.

Avoid opening new browser tabs for every scenario

Avoiding opening fresh browser sessions or instances for each test case is another technique to shorten the test execution time. Creating separate situations first is essential. By eliminating the need to establish browser preferences, clear cookies, and generate cache, utilizing the same browser session for many scenarios reduces setup time. This could take longer than doing the test itself.

It’s also imperative to refrain from utilizing the same browser session for various tasks. Memory would be used up because of the variables and other resources involved. It is not necessary to launch a new browser for every script, though. Alternatively, it is possible to group and run all relevant test scripts in a single browser session.

Use the API instead of UI interactions

In certain scripts, user interface interactions are required, but using an API to create test data is much quicker. For example, while utilizing an e-commerce platform, API tests can be used to add things to the shopping cart. For tasks that are required, like adding items for checkout scripts, user interface interactions can be omitted.

Some organizations use user interface (UI) tests to gather user feedback, although APIs make the process more straightforward.  Functional and API testing could be combined with designated functions. Through this integration, unnecessary UI interactions may be avoided and the end-to-end flow is streamlined.

Disable inconsistent visuals and pop-ups

Certain applications, including e-commerce websites, might become noticeably slower when a lot of graphics and pop-up windows load. Because validation is more focused on the features of the products than the actual images, the best way to increase efficiency is to prevent image loading. Most modern web browsers can restrict images. The testing time is greatly reduced by doing this.

Pop-ups are one of those unexpected promotional formats that are difficult to plan for or manage beforehand. It must create a URL parameter that disables all pop-ups to avoid having to wait for them to show up while testing. Testing can proceed more easily as a result, free from unexpected pop-ups or window interruptions.

Leveraging parallel testing

Sequential tests, meaning they run one after the other or one at a time, take longer to finish than a single-screen flow test. One of the best ways to shorten test run times is to enable parallel testing for test automation. With today’s automated testing tools, testers may set up and run several test cases at once, saving time compared to performing separate tests at different times.

Test teams can get quicker feedback on the overall performance of their application by running various test types in various contexts or configurations simultaneously. This enables them to increase test coverage, accuracy, and efficiency while also drastically cutting down on test execution time. In addition to improving scalability, parallel testing expedites the testing procedure as needed.

Get rid of any obsolete Code

Teams often miss unnecessary code when handling a large number of scripts or when apps are changed regularly. It is pointless to run test suites on these inappropriate codes. Teams need to remove unnecessary code since it makes it more difficult for them to comprehend and analyze the code base.

To deal with this, they should routinely verify the scripts’ operation and remove any outdated code. This process saves time, makes managing and monitoring the codebase easier, and keeps the codebase updated.

Utilize headless browser execution

Automation of tests can be accelerated by utilizing headless browser execution techniques. By turning off the graphical user interface (GUI), teams can use a command-line interface to run a browser’s full version. Headless mode allows teams to take advantage of Chrome emulation and other features to see how the application will appear on different devices. The browser functions exactly like a standard browser since it runs in the background, saving the user from seeing the web page. This method helps to get quicker execution times.

Leverage LambdaTest to accelerate test execution time

A crucial component of test execution cycles is the execution of test cases. The test execution cycle can be increased by streamlining the test execution procedure itself. Test automation is one of the most effective methods to increase the number of test execution cycles for improved testing. Thousands of test cases cannot possibly be manually run on multiple platforms repeatedly throughout each release. An appropriate test automation solution, like LambdaTest, can improve application quality, test execution efficiency, and testing efficiency.

LambdaTest is an AI-powered test orchestration and execution platform that allows users to perform manual and automated testing of web, mobile, and desktop applications at scale. The platform provides access to more than 3000 environments,  browsers, and real devices to perform both real-time and automation testing to speed up test automation execution time and deliver high-quality applications quickly and effectively.

It facilitates parallel testing, which enables the simultaneous execution of numerous test suites across a variety of platforms, devices, and browser combinations. Its capability for parallel testing allows testers to distribute test suites, shorten execution times, produce faster, more accurate results with less work, and release applications into the market more quickly.

They may automate a variety of testing tasks with LambdaTest, including integration testing, regression testing, mobile app, cross-browser testing, UI, API, and data-driven testing, among many others.
