Why Do You Need Test Automation?

The measure of intelligence is the ability to change -Albert Einstein.

You might be using manual testing for your application or business and doing reasonably well. Have you ever considered using test automation or want to understand if switching is a good choice? This article might help you to make a well-thought-out and informed decision.

Here, we discuss the capabilities of test automation, related examples, and the industries benefitting from it.

How Can Automation Strengthen Your Tests?

Using test automation, you can boost your application’s quality in less time, effort, and cost. Let’s dive deep into the details:

Impeccable Accuracy

Automated tests follow predefined scripts in every run, reducing the likelihood of human errors. Manual testing can be error-prone due to fatigue, oversight, or misinterpretation of test cases.

Example: A complex e-commerce application may contain different product tax calculations; a manual tester may miscalculate those. Taxes can be calculated accurately for various scenarios without errors through test automation.

Cost Reduction

While setting up test automation can require an initial investment in tools and frameworks, it often leads to long-term cost savings. Automated tests require fewer testers and less manual effort and time, reducing labor costs. Want to calculate your business’s ROI using a no-code test automation tool? Use our ROI calculator.

Example: Skilled manual testers are costly, and upskilling and training costs add to it, especially for complex projects. Use test automation to reduce the requirement for a considerable testing team to save labor and time.

Increased Efficiency

Test automation speeds up the overall testing process efficiently when compared to manual testing. These tests can be run in parallel, continuously, to reduce the execution time and errors substantially.

Not only this, some intelligent automation tools such as testRigor save your test creation time manifolds through its generative AI engine. Write only the test case description in the title, and the test steps get generated within seconds automatically. With testRigor, you save enormous maintenance hours and efforts because it provides self-healing capabilities to your test scripts.

Example: Consider a software application with hundreds of test cases. Manual execution of these tests would take days or even weeks. With intelligent test automation, these tests can be run in hours or less, enabling faster developer feedback and quicker software releases.

Handle Repeatability

Automated tests ensure that the same set of tests is run every time with the same consistency. Manual testing makes this challenging to achieve, where human error can cause differences.

Example: The login module is essential for a web application since it is the first step to accessing the application. Automated tests consistently repeat the same login scenario cases with different test data.

Faster Feedback

Automated tests provide rapid feedback to development teams in the CI/CD development cycle. This feedback enables quicker identification and resolution of defects, reducing the cost and effort required to fix issues in later stages of development or production.

Example: In the CI/CD pipeline, using automated unit tests, developers receive quick feedback after a code push or change. These tests ensure that the developers fix code issues early in the development cycle, saving effort and cost.

Quick Regression Testing

The ideal candidates in any test suite for automation are regression tests. Manual regression testing can be time-consuming, boring, and tedious for testers due to its repeated nature.

Example: After releasing a new version or functionality changes to an ERP system, automated regression tests can quickly validate that the existing functionality is unaffected. This test run ensures that updates don’t introduce unintended issues.

Comprehensive Parallel Testing

Automation allows tests to be run in parallel on various configurations and platforms, facilitating more comprehensive testing across different devices, browsers, and operating systems. Use parallel testing to execute test cases 24/7 with test automation tools and quickly achieve the required test coverage.

Example: Automation tests can be run on different browsers and mobile device combinations to ensure compatibility for a broader user base. Automation facilitates running these parallel tests on these configurations and platform combinations to save effort and time, which is unachievable through manual testing.

Validated CI/CD

Test automation integrates seamlessly with CI/CD pipelines. Automated tests can be triggered automatically with each code commit, ensuring that new code changes do not break existing functionality. testRigor provides seamless CI/CD integration; you can copy-paste already pre-populated script into your CI/CD pipeline.

Example: Code changes trigger automated tests in a CI/CD pipeline. If a test fails, the pipeline halts, and stakeholders are informed, preventing the faulty code from reaching production. This process ensures that only validated code is deployed.

Scalability Support

With new releases, as the complexity of software applications grows, so does the need for extensive testing. Automated tests can be easily scaled to accommodate the increasing scope of testing requirements. Use testRigor to test on the web, mobile, desktop, iOS, and Android. Integrations with leading infrastructure providers provide great scalability support for tests.

Example: When a mobile app starts supporting multiple languages for its users, test automation can easily handle many localization test cases. This test automation ensures the app works seamlessly for users globally.

Broader Test Coverage

You can create and test a comprehensive suite of test cases covering various scenarios and edge cases using test automation. This broader test coverage might be impractical to achieve manually.

Example: For a mobile banking application, you can cover different test scenarios, such as new user account creation, credit cards, bank statements, loans, payments, money transfers, etc., using test automation.

Detailed Data-Driven Testing

Automation allows for data-driven testing, where the same test script is executed with multiple test data sets. Thus, test automation helps validate application behavior under different data conditions.

Example: For a food delivery website, you can use test automation to calculate prices for different products by applying available discount/coupon codes, bank offers, and delivery charges based on location, tax rates, etc.

Improved Traceability and Reporting

Automated test tools often provide detailed reporting and traceability, making tracking test results and identifying the root causes of issues more accessible. testRigor offers detailed reports, screenshots, error text, and video recordings of the test execution to help you understand the application behavior correctly.

Example: Test automation tools offer customization and generate detailed reports containing test pass/fail information, logs, screenshots, execution videos, error text grabs, etc., to help you quickly identify and resolve issues.

Compliance and Documentation Support

Use automated tests to verify that developed software meets the government’s standards for sensitive industries such as health, finance, and banking.

Example: Test that the medical software complies with privacy regulations like HIPAA to protect patient’s health-sensitive information.
