Test Strategy is a Highlevel document and it is specific to 
each project.

Test strategy tells that what types of tests should be 
conducted on the system under test.

For example:

If the System Under Test is a web based Banking 
appllication/E commerce Application.

Then we need to conduct follwoing testins

1.Functional Testing
2.GUI Testing
3.Database Testing
4.Performance Testing
5.Security Testing(Mandatory)
6.Browser copatibility tesing
7.Usability testing(Optional)

If it is client server application:

1.Functional Testing
2.GUI Testing
3.Database Testing
4.Performance Testing
5.Security Testing(Optional)
6.Usability testing(Optional)........etc.

So the Test strategy will tell the types of tests to be
