Speed up test automation with reusable function libraries

An Introduction to Functional Libraries 

The primary objective of a strong test automation framework is to reduce the time and cost of testing. This can be achieved by incorporating reusability in test automation wherein you create a function once, store it in a library of reusable components, and call it to your test case whenever required. This is particularly useful when you perform the same function again and again while testing an application. This library of reusable functions is called the Function library(FL). A Function library reduces test maintenance effort and improves the productivity of the organization as testers can be free from repetitive tasks and can invest more time in value-added activities.

In automation testing, a Function library is a reusable component that serves a specific purpose. Instead of creating a new test case every time for every scenario like login, logout, and other functionalities, you can create a Function library for each scenario and reuse it across multiple test cases.

Opkey has a dedicated Function Library of reusable components that include repetitive user actions on an application.  In Opkey, a Function library can be called unlimited times in single or multiple test cases and other function libraries.

Key features of Function Libraries

• Opkey FL provides a comprehensive collection of pre-built functions for web, mobile, desktop, and API testing that allow users to create automated test scripts without writing any code. 

• It also provides integration with various test management tools, making it easier to manage test cases and track test execution results. 

• The FL includes functions, as well as the ability to create custom functions, making it a versatile approach for any testing scenario. 

• Using Opkey FL, testers can streamline their testing processes, increase test coverage, and reduce the risk of errors or defects in the application under test.

Types of FLs in Opkey

Opkey offers FLs for all kinds of testers like manual, automation, and coding testers. Let’s discuss the different types of function libraries in detail.

1. Manual function library

If you are a manual tester, this FL will provide the necessary functions to define the objectives and conditions of the test case. Post this, you can add test steps manually, and provide input data, expected output, and an attachment. You can also add other manual FLs that you have already created for a test scenario as shown below. 

2. Automated function library

This library leverages automation testers with the recording functionality for web, windows, mainframes, and mobile. Recording support for different ERPs is also available.

In addition, you can enhance your test automation by adding test steps to click, type, get values of UI elements, and perform other tasks.

Opkey helps you create FLs for long and complex test cases with the help of flowcharts. The test steps added can be seen in the flowchart view and you can add the steps in the flowchart too. The changes done in the flowchart will automatically reflect in the test steps.

3. Coded Function Library 

This library lets anyone with coding knowledge in Java write code for creating the test case. In a Coded FL, you can import packages that you want to use in your code, write the code, and create user-defined functions. 

Linking Function Library with test cases

Now you can link these function libraries with one or more test cases easily.

Here you can see a Gherkin test case.You can also link function library to such test case. Just right-click on the test step and link it with the function library.

So, creating a library of reusable functions and using it across test cases is a sure-shot way of achieving automation testing success. A Fucntional library will not only save your application testing time but also reduce errors in testing that are quite likely when you perform the same function again and again.
