How to Build a Scalable Regression Test Suite (Best Practices & Examples)

Regression testing is a must-have testing activeness. A quite common best practice is to build a regression examination suite consisting of many related test cases for a particular characteristic. This test suite is scheduled to run automatically after a code update to check if that exceptional feature is affected by the update.
 

The real question is not about how to build a regression tryout suite, but rather, on what criteria we should categorise our test cases. In this article, we will explore those criteria, as well as the best praxis in the industry for fixation examination.

What is A Regression Test Suite?

A regression test entourage is a collection of regression tryout cases that share certain characteristic. Test suites are usually grouped by feature-under-test, but that is not the only approach to progress test suites. We can actually group test suites by a rich variety of aspect, such as severity, area of impact, or type of tests.

The finish of a regression test suite is to:

1. Streamline the regression testing activities and achieve high efficiency.
2. Manage test cases in a more layered fashion
3. Faster test prioritization

How To Build A Regression Test Suite?

Step 1: Choose The Right Approach

When it come to any type of prove and not just regression testing, there are usually 2 major attack:

• : execute tests manually as a human examiner. For regression testing, this is a extremely counterproductive approach, as fixation examination is repetitive by nature. It makes perfect sentience to exactly automate it entirely.
• Automated regression testing: execute tests mechanically either by running an automated script or using an automation testing tool.

Building a fixation test suite falls into test management activities.

Test directionis the process of planning, categorizing, organise, coordinating, and schedule testing activity. It is the `` glue '' of all testing action.

If your squad follows manual examination, you can create a dedicated spreadsheet to note down the details of your regression test cases, with a column to exhibit which test suite each test case go to.

Such a table can look like this:

If your team follows automation testing, the practice is rather similar. However, there ’ s an constitutional matter with using spreadsheets for test case management: deficiency of testing-specific customization.

These test management creature usually integrate well with Jira.Here 's a list of tryout management tools with JIRA we have curated for you.

Step 2: Assign Tags/Taxonomy For Your Test Cases

Now let 's & nbsp; build our regression test suite!

All test lawsuit within a test entourage should share a certain & nbsp; characteristic, which is whyexam case tag& nbsp; come in really handy.

What are test suit tags? They are simply tags to represent the specific class (or test suite) that tryout instance go to.

For model, here are some category for you to take:

1. Functional Modules (or package part under test)
2. Test Case Types (e.g., unit, desegregation, scheme, acceptance)
3. Test Priority (eminent, medium, low)
4. Positive/Negative Scenarios
5. Test Environment (browser, OS, nomadic device, etc.)

You can portion several tags for one tryout causa. A test suite can be make using many tags. If you are using Google Sheets, you can easily filter the rag to quickly come at the list of test suit with specific tags that you require.

Step 3: Have A Naming Convention For Your Test Suites

For better management, it is highly recommended that you have a naming convention for your test suites. You should also feature detail documentation of the appellative convention for squad members to easily follow and identify your tryout suites.

Choose names that clearly trace the use or focus of the test suite. Opt for a consistent casing convention such as CamelCase or underscores. Include the specific category that the tryout entourage represents in its name. Also, make sure to strive for consistency in naming conventions across test projects.

How Katalon Fits in Your Regression Testing Need?

Let ’ s see how you can build a regression exam suite from a testing platform - Katalon.

is an innovative and comprehensive testing platform that unifies all of your test in one property. You can indite test, handle them, execute them across a rich array of test environments, then immediately generate visualizations of your testing effectiveness without any additional integrations.
 

To experience the power of Katalon, simply download & nbsp;. This is the primary space where you build and action your examination cases.
 

In Katalon Studio, on the top bar, chink on the [+] icon to create a new test cause.

After that, you can name your test case, provide a elaborated description for it if needed, and still allot them specific tags. These rag should get in handy as you part building your regression test suite and need to percolate out test cases based on specific conditions.

Here you can see we name the exam case as “ TC1_Verify Successful Login ”, postdate a defined naming convention (Test case ID + Test Case Purpose). Katalon Studio provides 2 test creation views: Manual and Script, which can be found at the bottom bar.

In the Manual mode, Katalon volunteer a rich raiment of built-in keywords for you to quickly craft trial cases. Simply click “ Add ” and prefer a suitable keyword from the dropdown list. Here we experience craft test cases from the & nbsp;Comment, Open Browser, Click, Set Text, Verify Element Present, & nbsp;and Close Browser.
 

These keywords, at their core, are just code snippets that automatically perform the comparable actions. You can swap between the Manual (Low-code) mode and the Scripting (High-code) mode for farther customization capabilities.
 

You can choose to execute those action topically, remotely, or & nbsp;.
 

You have make your test case without having to write a single line of code within minute, and this means you can likewise build C of similar test cases. To group them together, go to & nbsp;File & gt; New & gt; Test Suite
 

After that, name your test suite and give them a elaborated description.

Once execute, you can add your trial causa to those test suites.
 

How is that better than managing your tryout suite in a spreadsheet? As previously cite, you can execute and watch reports of your prove activities right within Katalon. It is a high level of streamline and integration that general-purpose spreadsheets won ’ t be able to achieve. Technically, you can, but that demand a lot of customization and maintenance, and over time the endeavor can grow to be counterproductive without some automation.
 

For regression testing, this intend doubled, or even tripled prove efficiency, at significantly less clip dog-tired testing, since a lot of the work has already been streamlined and/or automated.
