Difference Between Test Strategy and Test Plan

@Readers,

Here, would like to add some Difference between Test Strategy and Test Plan.

1. Test strategy defines "what is our approach to test that product/Project" where as the test plan defines "what to test, how to test when to test and who to test".

2. Test strategy is a company level document where as test plan is a project level document.

Hope, this will help you.
Thanks,
Trupti
