Why automate testing

The likelihood of a team having the capacity to run tests at exactly the same time is low. Automation makes this task super fast and enables teams to test rapidly without feeling the pressure. Automatic testing is required when you want to run the same test cases across multiple machines at the same time. Automation testing is also a good way to avoid human error in your testing. With automation, you can be sure that all tests are exactly the same, with humans you are allowing your simple error.

You can run tests manually on different devices, as long as you have enough manual testers. However, if you want to test your system by running tests simultaneously, you need to automate your testing. Essentially, you can set up a script to run automatically from a number of devices. It can improve quality, boost capacity and save your team time. In fact, there are specific situations where automated testing is viable. Remember those scenarios:.

Regression tests help the QA engineer detect if the API endpoint can still handle the same amount of requests or even more. A smoke test helps a QA engineer determine whether the deployed build is stable or not.

Often, this is seen as the confirmation step before proceeding with further testing. A smoke test holds a limited number of tests just to determine the stability of the build.

It acts as a quick verification check before proceeding. With black box testing, only the inputs and outputs matter. A tester should not have prior knowledge about the application and should not be given any form of documentation. The goal is to see how useable the application is when somebody tries to use the application for the first time. In short, black box testing is hard to automate but still a very useful type of testing to include.

A testing engineer who performs an integration test wants to know if two or more systems can work together integrate.

A system can be anything ranging from a database to an API. To give you an example, an integration tester wants to find out if the TweetDeck tool can still work on top of the Twitter API. If both products seem to work together, the integration test has succeeded. Many types of tests exist to help an organization to assess and improve the quality of their product.

Unit and functional tests are the basic tests every product should have in place. Regression testing is the most important type of test to maintain the level of quality for your product. By automating your testing process, your organization will not only save time and money but also deliver higher quality products. Manual testing should be avoided as much as possible.

Nowadays, an automated test suite can even simulate hundreds of virtual users all interacting with your application. This would never be possible with manual testing.

By Testim , November 06, Share on. Faster Feedback Cycle Without test automation, feedback for newly developed features can take a while. Integration tests are similar to unit tests in the way they are written and in their tooling. Integration tests can be an inexpensive alternative to E2E tests however, the return on investment is debatable when combination of unit tests and E2E are already inplace. Performance tests create measurements and assertions for these example cases.

Automated performance tests will run test cases across these metrics and then alert the team to any regressions or loss of speed. It is arguable that any tests that can be automated should be automated. It is a huge gain in productivity and human time cost.

With that said, there are times when the ROI of developing an automated test suite is not worth it when compared to executing a manual test. Automated tests are scripted and follow a sequence of steps to validate behavior. Exploratory testing is more random and tries unscripted sequences to find bugs or unexpected behavior.

While there are software tools to establish a software exploratory testing suite, they are not fully mature and widely adopted yet. It can be much more efficient to assign a manual QA tester and use human creativity to explore how to break a software product. A visual regression happens when a visual design flaw is introduced to software UI.

This could be mispositioned UI elements, wrong font, wrong colors or more. As with exploratory testing there are tools out there to write automated tests to catch these regressions. These tools capture screenshots from various states of a software product and then use OCR to compare them to expected results.

These tests are expensive to develop and the tools are not widely adopted. It can be much more effective to have a human look at something and see if there are any visual issues. There is no all-encompassing solution for automated testing. When planning an automated testing solution for your team, there are a few key considerations to make. Software products that release on fixed intervals, such as monthly or weekly, may find manual testing is a better fit.

Software products that release more rapidly will greatly benefit from automated testing since CI and CD are dependant on automated testing.

Test automation can easily execute thousands of different complex test cases during every test run providing coverage that is impossible with manual tests. Even the most conscientious tester will make mistakes during monotonous manual testing.

Automated tests perform the same steps precisely every time they are executed and never forget to record detailed results. Testers freed from repetitive manual tests have more time to create new automated software tests and deal with complex features. Even the largest software and QA departments cannot perform a controlled web application test with thousands of users.

Automated testing can simulate tens, hundreds or thousands of virtual users interacting with a network, software and web applications. Shared automated tests can be used by developers to catch problems quickly before sending to QA. Tests can run automatically whenever source code changes are checked in and notify the team or the developer if they fail. Features like these save developers time and increase their confidence.

Executing repetitive tasks with automated software testing gives your team time to spend on more challenging and rewarding projects. Team members improve their skill sets and confidence and, in turn, pass those gains on to their organization.

While automated testing has been considered essential for organizations, both large and small, to implement in order to deliver outstanding software and stay competitive in the industry, it can be tough to get started. Outlining an effective roadmap, building robust frameworks, choosing the right tools, and measuring the potential monetary impact that automation could have on your delivery lifecycle are all critical components of any successful automated testing strategy, but each step presents its own challenges and costs.

In simplest terms, automated testing involves tools or programs used to automated testing scripts. There are many different types of software testing that can be automated.
