TESSY

It’s a vital instrument for integration testing because it can conduct integration and unit tests with embedded software. It is accountable for the whole test structure, which includes traceability, requirements, test management, and coverage measurements. TESSY helps us determine the coverage of an application’s code. Creating test cases using CTE (classification of a tree editor) is possible. We can also utilize TDE to alter the test information (test Data Editor).

Key Features:

• It is also able to request a floating license.
• TESSY’s TIE (Test Interface Editor), the TDE (Test Data Editor), and workspace comprise the three primary functions.
• It’s used to evaluate the function’s interface as well as to specify the parameters that are used by the process.
• Programming languages C++ and C are both supported by TESSY.
• It creates a report based on test run outcomes.

Protractor 

It’s an open-source, end-to-end testing framework integrated into JavaScript, designed to work with AngularJS and Angular applications.
