How to create Test Automation Strategy: Best Practices

Test automation has go a critical practice in modern software development, helping teams accelerate liberation cycles, improve accuracy, and integrate seamlessly with agile and DevOps workflow. While manual testing still plays a purpose, relying solely on it can slacken down delivery and limit efficiency.

This guidebook explains what test automation is, why an mechanisation strategy is indispensable, and the best practices for building a robust test automation framework that motor long-term line value.

What is Software Test Automation?

Software Test Automation is programmatically verifying the expected result and actual result without manual interposition. Test Automation needs specialised testing tools to compose and execute the scripts.

This brings us to the next question & # 8211; Why do you need? Manual testing is time-consuming and resource-heavy. Modern are automatise, and this assist accelerate the freeing cycles.

With manual testing, the release should be held up until you hear from the testing team. Though the development is completed on time, examine can slacken down your release. On the other hand, automation testing doesn & # 8217; t take much time and imagination.

Advantages of Automation Testing include:

1. Saves cost
2. Fast Development and Delivery
3. Accurate Results
4. CI/CD or DevOps Integration

Why do we need a Test Automation Strategy

The Test Automation Strategy delimitate the success of test automation, and a well-defined mechanization scheme render the better upshot. The organization/team should spend a good amount of clip delimitate strategy. Without a good automation strategy, automation can lose focus.

Listed below are a few things that can go wrong in absence of an automation strategy.

• Loss of Business Value:If the doesn & # 8217; t bring any business value, then Return On Investment (ROI) will be negligible. No organization supports something which doesn & # 8217; t get occupation value or if there is no. Automation scheme should be clearly defined in a way that brings higher concern value than expected.
• Lack of Vision:The automation strategy delimitate the long-term finish and vision, without which you might end up wreak multiple tools and trash them more frequently.
• Wrong Technology:In the absence of an automation scheme, you will end up using the wrong puppet and technology. If you choose the incorrect tech stack and tool, in the long run, you might face a lot of challenges, or you might even need to scrap existing and build something new from moolah.
• Risk Analysis:The strategy also helps to predict the danger involved in trial automation. The strategy will receive information about if there is a hazard, how it can be optimise, workarounds, and alternatives. Without a scheme, you will have no clue of the jeopardy which can arise in the hereafter; when it arises, it may be too late for you to observe the solution. Read about.

Best Practices to progress a Test Automation Strategy

1. Define Goals

Before starting automation, you need to be clear about your long-term and short-term goals of tryout automation. You should distinctly put the road map and discuss it with high management and stakeholders. Some of the pointers might help you to specify the goal.

1. Why are we see test mechanization for this labor
2. The expected business value from automation or ROI
3. The scope of mechanization
4. A high-level procedure to render the automation
5. The planned percentage of automation (In a gradual manner ex: one-quarter wise)
6. The end goal of automation

2. Test Approach Planning

There are different levels of testing, many clip automation is confused with, but there are many levels. The good approaching is to make.

• Unit Testing:is the backbone of the mechanization strategy, and mistaken failures are very less. Though Unit testing is part of white box testing, having full coverage of unit examine reduce the regression. Unit testing should be compulsory for any features that are be develop. The modern infrastructure provides an alternative to put the quality gate where you can define the minimal percentage of Unit Test coverage before force it to the repository. The Unit Testing coverage percentage typically swan from 80 % to 90 %; however it depends on the application framework, complexness, and type of application.

• Integration and API Testing:Nowadays, nigh all organizations postdate API-driven architecture for maturation. API testing act as middle-level or integration examination, and it & # 8217; s easy to achieve. The open API testing technique produce outstanding output. API testing helps to validate the business logic to a great extent. In the absence of an API, reckon having integrated component examination.
• UI Testing:focussing on UI elements. Visual Validation testing is one example of UI Testing. The UI test mostly validates the styles, layout, conjunction, fonts, etc. The well-defined UI testing facilitate to reduce UI bugs and render a suave User experience (UX).
• End to End Testing:The most focused country in test mechanisation, end-to-end testing concenter mostly on functionality and workflow. The mostly repeat the user behavior using model. This is the exact replacement for manual examination. End to end Testing should be well publish. This also requires seasonable maintenance to make accurate output, so while defining a scheme, you demand to see it.

Former Areas of Testing to Focus on:

• :The Testing team needs to act with the product and business team to realize the crisscross browser requirements. Your application should be compatible with different device such as Chrome, Firefox, Edge, Safari, etc.
• :The Cross browser can be multiple browsers on the same operating system or multiple browsers on multiple operating systems; if the covering is indorse by multiple go systems such as Windows, Mac, Linux, iOS, Android, etc, then you need to define the plan to achieve them. You need to see both the native app and browser. You can consider a cloud-based platform likeBrowserstackto achieve such requirements with ease.

3. Choose a Framework

Once you know the concern value, the most critical part is the character of framework you choose. There are different types of; you need to discuss them with the squad and choose the correct one.

Linear Automation Framework (Record & amp; Playback)

The works when the exploiter simply records the test and executes them after. The record and playback tool are well beseem for beginners. The platter and playback tool is not recommended as it has a lot of restriction.

Pros:

• Easy to set up
• Easy to automate the handwriting
• Less technological knowledge required

Cons

• Requires a lot of maintenance
• Almost impossible to use in the long run.

Data-Driven Test Framework

The data-driven testing but separates the data and literal tests. In a, the data is stored in external files like CSV, JSON, etc., and later it is utilise in your handwriting dynamically.

Pros:

• This framework is best when your application has frequent changes in data
• Running the same tests with multiple sets of data is leisurely and requires less endeavor

Cons:

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

• The data-driven model requires good technical skills
• Need to pass time separating datum, preparing datum files, and utilise them in your scripts.
• Code reuse will be limited
• Consumes more time

Keyword drive model

In, the keywords are map with the action performed on GUI. For model, the keyword & # 8220; enter the username & # 8221; typewrite the username on GUI. The keywords are separated from examine logic and stored separately whenever the keyword is encounter, the mapped purpose will be telephone to perform activeness.

Pros:

• The keyword-driven framework aid to achieve a high degree of code reuse.
• Easy to use for beginner-level quizzer.

Cons:

• Keyword driven framework is time-consuming
• High setup cost.
• Rich technical expertise is command.

Page Object Model

is the about popular framework design strategy in automation. It is also called POM. The page object framework creates the object repository for storing the HTML elements. The HTML constituent (Objects) of each web page are store in a freestanding file; then, the page objective will be used for make test scripts.

Pros:

• The page object model offers increase code reuse.
• Ease of maintenance
• Good legibility

Cons:

• The Page object poser can not be used for multiple projects as it is not generic
• Takes time to set up
• One should be technically skilled to set up the framework

Modular driven framework

The modular-driven model divides the test cause into small faculty. The module can be a small-scale set of use, or a set of features, that the application has. Tests are create individually and combined to do a bigger test suite. The lord script generally name the requisite scenarios/modules.

Pros:

• Ease of maintenance
• Easy to develop the test script as they are smaller

Cons:

• The limit up framework can be challenging
• Hard-coded datum ends up duplicating tests

Library architecture model

The library architecture model is similar to a modular-driven framework; In gain to a modular-based framework characteristic, it provides the extra welfare of common functions. Similar tasks which can be reused in multiple places are severalize and stored in mutual files/directories.

Pros:

• Provides a high measure of code reuse
• Maintenance doesn ’ t require much time

Cons:

• Expert-level technological skills are take to achieve this framework.
• Writing common libraries and separating them makes the framework more complex.
• Reduced readability

Behavior Driven Framework

The BDD model use the gherkin language format (Given, when, then). The credence criteria given by the product team will be mapped to the test cases. The BDD model carry the feature files. Each feature file will have a set of scenarios in apparent English words. These scenarios in the feature files are mapped to the footstep definition files to pen the executing logic.

Pros:

• Clearly delineate scenarios
• Full level of code reuse
• Easy to understand for non-technical squad
• Easy to map the information into test scripts

Cons:

• Test case creation occupy time
• Difficult to maintain
• One needs to understand the requirement distinctly before writing the test cases.

Hybrid model

The can be a combination of any of the above-mentioned frameworks; as you are aware that every framework has some advantage and disadvantages. Based on the required set of features, one can combine the above type of fabric to create a hybrid model.

Pros:

• Adds flexibility to your model
• Increases the code reusability
• Easy to preserve
• Customization of reports and analysis

Cons:

• Requires in-depth savvy of testing
• One must be extremely skilled to achieve this model
• A poorly designed framework can become worthless to an organization

4. Evaluate and Choose the Tool

The essay tool should be carefully appraise, and pick the right creature. Remember, & # 8220;Never choose the best testing puppet in the market; incessantly choose the good testing puppet for your organization & # 8221;. That means the best tool in the marketplace may not be the best fit for your administration.

While evaluating a testing puppet, you must study multiple things, such as

1. The scope of the test automation tool
2. Expected functionality from the test mechanisation tool
3. Supported platforms/browsers
4. Need to judge if it fits your domain
5. Cost
6. The programming words support
7. Community support and certification
8. Learning involved

The automation tool evaluation is typically perform by pick a set of tool that fit good into your organization/team and then by performing the Proof of construct (POC) to decide.

The puppet will be valuate by answering a set of query as mentioned above and then by indite a little few trial cases. The proof of concept can also involve integrating with CI/CD pipeline to evaluate how well it fits into the.

Once you measure and choose the tool, you must discuss it with management by clearly showcasing facts such as limitation, advantages, etc. One must not be predetermine based on his expertise and scholarship, the tool must be evaluated as per the organization & # 8217; s requirement.

5. Test Automation Environment

You need to be really clear about where the tryout data will be store, where the automation execution takes place, how the report will be store and shared, how long the old report will be stored etc. You should likewise know which environment the application under exam will be used for validation, such as dev, staging, production, or all of these, etc.

If you are adopting DevOps practices, then the constellation and initiation of the pipeline come in place.

6. Risk Analysis

It is essential to canvas the risk and convey it to management. Automation testing may have some jeopardy free-base on the creature and strategy you are habituate. For illustration, if you are create a separate certification for test automation and if you decide to use the production environment, then imagine the risk. If such a jeopardy come, what is the mitigation plan? Before starting to quiz automation, you should bode the risks that automation brings and the mitigation plan, etc.

7. Define Automation Team Working Strategy

This is the high-level approach to planning the automation; this include who is play what role. You can postdate the sprint-1 strategy for automation. It can also include automation test instance review processes.

• Team members & # 8217; roles and responsibilities, who will be heading, point of contact, etc.
• When test cases are automatise, for example, like sprint or sprint & # 8211; 1
• How the testing members are divided, some follows a separate automation team, some combine manual and automation testers, and some organization postdate the scrum team, where dedicated mechanisation appendage for each team.

8. Learning Goals

The learning curve has to be evaluated while choosing the puppet; if you are switching from one tech stack to another, or initiating a manual tester to automation tester transition, so there is learning involved in it. When there is learning involved, productiveness can not be 100 % as squad members necessitate to spend time learning. So, you want to set a finish for learning. The management should too be mindful of this, as productivity may not be as expected until the learning completes.

9. Create, Execute and Maintain Tests

You have chosen the tool and engineering. The correct tool is in spot; at this point, you can bring automation into reality by implementing them.

1. Start creating the automation hand.
2. Decide upon what can be automated and what can not.
3. Start with the about critical features and quick wins.

Once you create the test cases, fulfill them much. Timely maintenance is ask for automation test cases as there will be active development in the ground.

Create, execute and maintain repeats as your day-to-day work.

10. Execution Plans and DevOps Integration

Once you have the test automation scripts ready, you need to plan for execution.

1. Consider creating examination suites like smoke, fixation, sanity, etc.
2. Define performance scheme; for example & # 8211; smoke needs to run every day, regression doubly a hebdomad, etc.
3. Have a feature-wise test suite; whenever there are feature alteration, there is no motivation to execute the whole regression suite; one can just execute solely the required exam suites.
4. Consider DevOps integration which makes quizzer & # 8217; and developers & # 8217; jobs easier.
5. The DevOps consolidation also cut the dependency of the testing team; anybody can execute and get the report.

11. Reporting

The reporting is most important in the examination automation creature.

• The reporting should not moderate any technical item as it may confuse the stakeholders.
• The report must have numbers of full test cases, surpass, failed, etc.
• Consider get graph, trends, etc., to make the report more attractive.
• The story must be understandably understandable for any non-technical person
• You must define a strategy around report sharing, like recipients, when to share and how often, etc.
• Store a account in a commonplace; one should be able to entree it anytime when needed.

12. Review, Analyze and Retrospect

This is a never-ending task; you need to continuously review your test hand, understand what is do false failures, and translate what is touch test case creation. How can you do it ameliorate? This job is not only for test case creation. This may include modifying the unscathed automation strategy as easily, but this should not deviate from your original destination.

Test automation can be the only way of try in your organization; the success of exam automation depends on how well the scheme is delineate and how it is implement. Any mistakes that you make while building a strategy can make a big impact. You should be very careful and unbiassed while build a test automation scheme. The direction should be aware of both good and bad. Ask for opinions and feedback, and try to avoid create determination independently. Decide base on collected feedback and opinions.

BrowserStack permit you to perform manual and machine-driven tests using different fabric and languages. You can run,,,,,, and XCUI tests seamlessly on 3000+ devices and browsers.
