Testing is a key phase of the Software Development Life Cycle(SDLC). Testing can be broadly categorized into Blackbox Testing and White box testing. 

The Whitebox testing mainly focuses on the code path, logic, and actual implementation, using unit-level or component-level testing. On the other hand, black box testing is carried out considering the user workflows in mind. Blackbox testing is carried out at the feature level or application level. 

Black box testing can be done with or without any tools. However, the black box testing tools make the testing process more streamlined and help to discover more bugs.

What is Blackbox testing?

Blackbox testing is a type of testing, that is performed without any knowledge of system internals. Black box testing is performed considering the end-user journey. The tester thinks like an end user and performs workflow testing.

Types of Blackbox testing

Black box testing can be further divided into

Manual Testing: Tester uses the predefined test case lists from the repository and performs the action on the application. 

Automation Testing: The Tester writes the automation code/actions and the automation script will take care of the execution of test cases and feedback on the result.

Best Black Box Testing Tools

Both manual and automation black box testing can use tools. There are various tools available in the market. Most of the tools are dedicated to automation testing. However, there are tools that are exclusively made for manual testing. Let’s discuss in detail the top tools for Black box testing.

Black box testing can be carried out using a manual approach or an automated way. In earlier days automation required skilled resources however with the recent development, automation can be done using plain English language. Tools like Testsigma don’t require any programming skills or technical knowledge. The tool is most favorable to manual testers who can directly jump into automation with their limited skill sets.
