Every step of the manual testing process is completed by a human. Before an application is released, testers run through all of the necessary testing procedures by hand.
Automated testing, on the other hand, involves the use of automation tools and scripts written by testers. With test automation, testers can save test scripts as assets and use them again later, cutting down significantly on the time and effort required for repeat runs.
Why Should We Switch From Manual To Automation Testing
Many of the difficulties associated with manual testing can be eliminated through the use of test automation, which is especially useful in Agile projects.
#1) Test Reusability
Multiple test cycles and test environments do not preclude the re-use of automated test cases and test suites. Because of this, instead of manually running regression tests after every application update, you can simply run automated regression test suites to ensure that no regression defects have been introduced. One of the primary benefits of automating processes is that it makes operational errors less likely to occur.
#2) Higher Test Coverage
Automating the execution of tests frees you up to focus on new use cases and expand the number of test cases used to manually check and validate the AUT (AUT). For the sake of product quality, you and your teams can now devote more time to exploratory testing.
Parallel or simultaneous execution of automated tests across several platforms and devices is also possible. The more tests that are run, the more probable it is that regression flaws will be detected and that business requirement will be confirmed.
- Earlier Feedback and Bug Detection
It takes more time, money, and effort to fix bugs that make it into production. As a result, teams are moving to the left in order to reduce costs by finding flaws earlier.
Automated testing can begin alongside the development process if done properly. Before submitting changes to a shared repository, developers can run local unit tests to ensure everything is working properly.
The CI process may also include unit tests. The pipeline is activated when a commit is made, and at that point, automated unit tests, followed by integration and/or system tests, are executed. Developers can get input early on, find and solve errors faster, and keep them from making it into subsequent phases.

#4) Going Beyond Manual Testing
When it comes to time-consuming and resource-intensive tests like performance testing, test automation can accomplish what manual testing often cannot. It’s a great alternative to manually simulating millions of queries to the AUT’s server-side from a variety of platforms and devices.
Tools designed for automating repetitive tasks can complete multiple tasks in parallel more quickly and accurately than people can. Machines don’t get tired or bored as people do, so they don’t make the same kinds of mistakes that people do. This means that the test findings can be trusted and obtained quickly.
Note:
Keep in mind that test automation is effective over time. There is a high out-of-pocket expense upfront, and it takes some time to get everything running smoothly, provide measurable outcomes, and reduce the cost-to-benefit ratio.
This means you should give some thought to the circumstances facing your squad. Moving from manual to automated testing isn’t always the best option. Spending money on test automation might not be worthwhile if your team:
Accepts assignments of short duration.
creates easy-to-implement apps that can be finished in four to six months.
Tests should not be conducted frequently.
Use manual execution to test a wide variety of complicated scenarios.
Transition From Manual To Automation Testing With Confidence
Step 1: Design Test Automation Strategy
The lack of a well-defined, objective-based test automation approach is a common reason why many teams struggle. It helps ensure that everyone on the team is on the same page. As a result, everyone is aware of the predetermined objectives and strategies and may assess whether their current course of action is effective.
Without a well-defined plan, teams are more likely to lose focus, settle for subpar solutions, and fail to leverage test automation to its full potential.
One useful perspective is as follows: Automating tests is analogous to developing and owning one’s own software with which to test other programmes. In the same way that software development requires a well-defined strategy and roadmap for implementation, so too must this endeavor be managed.

Step 2: Enrich Test Automation Foundation
All the fundamentals of test automation must be known, including but not limited to: Agile and DevOps approaches, framework construction, the automation pyramid, the architecture, the automating methods, reporting, and analytics. If a group lacks a solid base, it will struggle to put its plans into action.
Furthermore, you should examine specific automation solutions or testing tools, the talents they demand, the challenges they answer, and the methods by which they accomplish their goals. Additionally, never stop expanding your knowledge.
After a while, many groups just stop adding new information to their knowledge base. Since the market is always morphing in response to emerging technology, trends, and solutions, ceasing your pursuit of knowledge will only hasten your demise.
Although there are a lot of free materials available online, paid testing courses are worth the cost. Experts teach by showing how automation solutions actually perform in the real world.
Following are examples of widely read and reputable sources:
Katalon Academy is a free online resource for learning the fundamentals of test automation, gaining marketable skills, and using Katalon tools in your own projects.
Udemy is an online marketplace for courses where you can learn anything from the basics to advanced skills from professionals in their fields.
Coursera is a website where you may take classes and do guided projects to test your knowledge and gain expertise. Explore the internet for additional helpful resources to understand test automation.
Step 3: Advanced Programming Skills
When it comes to building a framework and writing automated test scripts, many test automation solutions demand coding expertise. Many groups, then, seek out prefabricated testing instruments featuring low-code capabilities as a means of getting through these stumbling barriers.
However, without coding knowledge, testers are limited to using built-in keywords, record, and playback features, or the manual mode with an easy-to-understand user interface (UI). However, this state of affairs cannot persist indefinitely.
Over time, you’ll need a developer or at least an automation tester with coding and programming knowledge to help you design more complicated test cases, tweak scripts, construct new keywords, maintain tests, and troubleshoot failing tests.

Therefore, if your team wishes to make the transition from manual to automated testing, you should look into hiring testers with a programming experience or encouraging the team members to learn and improve their coding skills.
Step 4: Evaluate and Choose The Best Fit Testing Tool
There are literally thousands of tools to choose from, making the process of making a decision very difficult. The success of similar teams is a major factor in the decision-making process for many teams when selecting a tool. However, just because a certain tool is effective for one group doesn’t indicate it will be the same for yours.
Think about the abilities and limitations of your group. So, to help you analyze your options and pick the one that works best, here are some questions to ask:
To what end are you attempting to work? It is important to plan out your automated testing strategy by deciding on the AUT (web, desktop, or mobile applications) and the features you need to test (for test creation, execution, report, etc.)
Is there a plan for who will operate the apparatus? For manual testers, a low-code approach is preferable.
Does this work with the processes and tools already in place on your team? To cut down on workaround time, try to find automation products that have native integrations.
Is it prepared for the future? Think about your team’s ability to grow into the new tool you’re considering, and be sure it can handle your anticipated needs before switching.
When planning, how much are you willing to spend? Commercial solutions are quick to start up and easy to use, while open sources are free but require time to set up and develop the test automation tool.
In which locations might you find help? Having access to helpful customer service or an active community can be a huge time saver when troubleshooting technical issues.
Advice: If you’re starting from scratch, a ready-made tool like Katalon Studio that supports both low-code and scripting is the way to go. The most challenging aspect of beginning test automation is constructing a framework and features, both of which may be avoided using this.
As an example, manual testers can immediately begin automating test cases and recording test objects with low-code tools like Record and Playback. With time and practice, they can learn to write test scripts, create additional custom keywords, and make use of more advanced capabilities.
Also, after settling on a tool, it’s important to test it out. Get everyone on the team to participate in a short sprint centered around the tool. At the end of the sprint, compile all of the comments and decide whether or not the tool is up to your team’s usual standards.
Step 5: Start Small and Scale With Confidence
If you’re trying to make a change, don’t sabotage it by trying to do too much, too quickly. You don’t need a 50-page strategy document that includes every detail of your endeavor.
