TEST PLAN:A test plan is a systematic approach to testing a
system such as a
machine or software. The plan typically contains a detailed understanding of what the eventual workflow will be.Test plans in software development.In software testing, a test plan gives detailed testing information
regarding an upcoming testing effort, including? Scope of testing ? Schedule ? Test Deliverables ? Release Criteria ? Risks and Contingencies.
TEST CASES:Test cases is a sequence of steps to test the correct behavior of a functionality/ feature of an application
A test case should have an input description, TestSequence and an Expected Behaviour.

A test strategy is about what you want to test.

Test logistics are about what resources are needed to test what you want to test, the way you want to test it.

A test plan couples those two items, factors in the project plan and yields how and when the testing will be accomplished.

TestCase:"Test Case is a Document Where one can find all the prerequisite conditions like testdescription,testdata,teststeps,expectedBahavior.It is Started from erlier stages of the Software Development Life Cycle.Test Cases are written in order to know wether the application,project or product which is in under development (or) Developed, is working Properly or Not.
