Add github actions including all the tests

Is your feature request related to a problem? Please describe.

Since we will soon add new features to the project, we need to test the PRs. Adding github actions which includes all the tests will verify and help us in checking its testing quality.

Describe the solution you'd like

• Create a folder .github/workflows and add the file named tests.yml.
• You must include all the tests.

@keshakaneria As there is no test present on this Repo. I think we had to make more issues to implement the test and code coverage. After that when there will be a test we can make the workflow for testing. So I am adding on:hold label in this.
