The time and space of software development is changing rapidly.
The requirement for computer software and mobile applications is changing rapidly.
DevOps following the XP framework relies heavily on TDD.
So, if you are in such a project, the following tools can help.
What Is Test-Driven Development (TDD)?
Upon testing, the program obviously fails.
This failed test becomes the subject of further corrective actions.
For example, the programmers must write minimum lines of code so the test case scenario passes.
Codes generated through the TDD process are more maintainable and reliable.
This iterative failed tests and passed tests ensure a feedback loop between the teams involved in Agile development.
In DevOps, TDD supports the overall goal of delivering high-quality software at a rapid pace.
Collaboration and communication is an important aspect ofAgileand DevOps.
Test-driven development also facilitates this within cross-functional teams.
Its major features are as outlined below:
Mockito
Mockitois an essential mocking framework for TDD projects.
It lets you and your DevOps team create mock objects for testing purposes.
This test-writing tool simplifies the process of isolating dependencies during a code test process.
Also, you’ve got the option to easily verify the behavior of the test object.
Mockito allows you to mock external dependencies as well.
For example, you’re able to create mock cases of databases or web services.
Then, use these mock subjects to further test mock objects of small test functionalities of your software.
Various DevOps projects often use JUnit 4 along with Mockito to facilitate test-driven and behavior-driven software development.
It also offers the TestEngine API you gotta develop testing frameworks on a JVM.
pytest
pytestis a testing framework based on Python.
DevOps and Agile software developers use it to easily write and scale test codes on Python CLI.
Cucumber scans the specifications written in text-based formats.
These specs are mainly functionalities that must be provided by the software you are developing.
There could be multiple specifications in different scenarios.
The tool will go through all these and validate if the code conforms to the specs.
It generates a report with failure and success scenarios.
TestRail
TestRailis a testing workspace-like tool for all of your DevOps projects.
It creates an ecosystem of centralized code testing and QA platform using the TestRail Quality OS.
There are multiple testing libraries in RSpec that can work together or individually.
These are rspec-expectations, rspec-rails, rspec-core, and rspec-expectations.
Cypress
Cypressis a cloud-based testing tool built for modern web apps with next-generation features.
Jest
Jestis a JavaScript testing software that developers commonly use for test-driven development (TDD).
It also has the necessary API calls for coverage reporting.
It offers a simple and expansive syntax library so developers can easily create and run tests.
you’ve got the option to run Mocha directly on the web web client with the help ofNode.js.
It comes with extensive support for asynchronous testing.
Hence, it allows for testing code that concerns callbacks, promises, or async/await functions.
Final Words
Now you know which test-driven development tools you must use in DevOps-driven extreme programming projects.
