Test scripts are those comprehensive instructions that specify what has to be done and anticipated by testers throughout the execution of a test case. They are necessary to guarantee the performance and caliber of software systems and products. Automation testing allows software testers to test each step on various devices extensively.


However, you must think, how can one create efficient test scripts that address every case and requirement? Well, here are some pointers and best practices to assist you in writing test scripts that are comprehensive, clear, and concise.


Let’s start with some basics first.

What is a Test Script?

Test scripts are a detailed list of all the tasks that need to be completed and evaluated on different user journeys. It outlines every step that must be taken and the desired results. The testers can then methodically test each step on a range of devices. Scenario testing is a test that adheres to a set of test steps. The test script must contain the actual things to be executed and the expected results.


This story begins with the test script, the most comprehensive way of document testing. Generally speaking, when someone talks about test scripts, they mean a detailed account of every action and piece of information needed to execute a test. 


Typically, a script consists of steps that explain in detail how to use the software, including which buttons to press and in what order to carry out a specific task. The anticipated results for each step, such as observing a change in the user interface, are also specified in these scripts. For example, “Click the ‘X’ button,” with the sample result “The window closes.”


When a tester starts a new job, they might need to learn more about the program, the product, or the business sector. Scripts could help close this gap. If the tester carefully follows the instructions, which include typing the text “ABC,” clicking the submit button, and double-checking that the form was introduced. The value was stored, and the test concept will be adequately covered to be termed “tried.”


Programming languages such as Java, Perl, Python, Ruby, and VB script are frequently used for scripting. We can check the application’s functionality by creating scripts for each feature. 


Understanding the purpose and limitations of the test is necessary before writing test scripts. This highlights the studied characteristics, anticipated outcomes, and possible dependencies or hazards. New functionality is added to ongoing software projects, pages are redesigned, and the user experience changes almost regularly. This helps ensure that the app keeps evolving with time and according to the user’s needs. 


Testers must continuously change their scripts to match the new product to stay effective over time. Again, test scripts are an essential part of developing an app. Scripted tests are frequently designed to test the same thing repeatedly, using the same data and processes each time the test is executed. 

Benefits of Test Script

Let us now look at some benefits that test scripts offer:


● Make sure everything is noticed: The most dependable method for ensuring everything is seen during testing and that the outcomes match the intended testing strategy is to use the test script.

● Users’ performance matters: Test scripts become crucial when there are precise user requirements.

● The tester freely peruses the product: Test scripts can be handy when the tester uses the program without restriction and believes a function will produce the desired result when it doesn’t. 

● Reduces opportunity for error: A well-written test script minimizes the chance of error during testing. 


How do you create Test Scripts?

In this section, we will tell you how to create test scripts. 



With this method, the tester has to write any code and refrain from capturing user input. Coding is necessary to correct problems or adjust automation behavior. This strategy is easier to handle because all the code is available, rather than starting and building a test script from scratch. This approach is typically well-liked for use with straightforward programming languages like VBScript. 


The steps a software tester must take to create a test script using the Record/playback approach are listed below-

1. Choose a tool that works well for the record/playback technique. 

2. Execute a series of user commands within the program.

3. Take note of the user’s behaviors.

4. Make a test script to “playback” or automatically repeat the actions. (This is sometimes called the test script’s stimulation section.)

5. Depending on the objects to be tested, add stages to the Script. (This is sometimes called the test script’s validation section.)


After completing the first four tasks, the tool will-

● Determine which user interface elements are being tested.

● Permit the hierarchy of objects in the application being tested to be seen by testers. 

● Testers can modify the automated tests by specifying the user actions and selecting the things.



Keyword/data-driven scripting method

This approach involves both developers and testers. However, they have well-defined tasks. Using keywords, the testers should define the test. The testers must understand the underlying test code. Using the keywords supplied by the testers, developers create and modify the code for the test script.

The steps a software tester must take to create a test script using the Keyword/data-driven scripting method are listed below.

1. Choose an appropriate tool for the data-driven/keyword scripting technique. 

2. Give a list of “keywords” that characterize the actions of end users. 

3. The simulation portion of the test script consists of a single term that characterizes the user activity.

4. The validation portion of the Script uses a collection of keywords and values of anticipated data for each UI component being tested.

5. Create a test script that runs the necessary operations on the application that is being tested.


Writing Code Method

This method allows us to record or replay and create a test script. The testing scripts should be written in an introductory programming language, like Ruby or JavaScript. It is optional for the chosen programming language to be the same as the language used to create the software.


The steps a software tester must take to create a test script using the Keyword/data-driven scripting method are listed below.

1. Choose an appropriate tool for the Writing code technique. 

2. Automate the simulation portion of the test script using the testing tool’s built-in instructions to pick objects.

3. Find the UI items related to the validation section.

4. Write code that verifies and examines each UI object’s predicted outcome.


Tips to Write a Test Script

The following are some crucial pointers for writing a test script:



You should have a clear test script if the tester must repeatedly ask the project manager for information regarding the application. Without a doubt, this is a waste of time and money. To prevent this, you must ensure that every test script step is understandable, concise, and cohesive. This maintains the testing procedure’s fluidity. The test stages are the core part of test scripts. These specify what testers must do and what outcomes they should expect.



Write a test script that asks testers only to perform a single, predetermined activity. This guarantees accurate testing of every function and prevents testers from skipping any stages in the software testing procedure.


Carefully planned

You must pick which paths to test by placing yourself in the user’s shoes while writing the test script. It should be within your creative ability to foresee every possible way consumers might take when utilizing a system or program. The language used in the test phases should be clear, exact, and concise. 


Moreover, they must be sequential and numbered to eliminate doubt or misunderstanding. The test procedures should cover all needs and potential eventualities, including positive and negative boundary instances.



Test scripts should adhere to a uniform standardized framework that facilitates comprehension, drafting, and execution. The elements test ID, name, description, test data, test steps, expected results, actual results, and status are all part of a standard structure for test scripts. You can use a template or an application to write and manage your test scripts in an orderly and structured manner.


Usage of Test Data

The input that testers use to test scripts is called test data. Test data must be sufficient and diversified, encompassing a range of values and types. Preparing and storing test data in a different file or database is best. Test scripts should avoid hard-coding or duplication by referencing and reusing test data.


Review Test Scripts

Test scripts need to be evaluated and validated before they are considered finished. Examining test scripts includes ensuring they are accurate, comprehensive, and consistent. Testing test scripts for functionality, usability, and performance is known as validation. You can find and correct any mistakes, gaps, or inconsistencies in your test scripts by reviewing and validating them. You can check and assess your test scripts using walkthroughs, dry runs, and peer reviews.


Update Test Scripts

Test scripts are dynamic. They must be updated and kept up to date while the system or software undergoes evolution. Test scripts must be updated and maintained to reflect changes in the system or program’s specifications, functionalities, or features. You can ensure that your test scripts are consistently accurate, dependable, and relevant by updating and maintaining them. To update and maintain your test scripts, use version control, change management, or traceability technologies.
