Test Analysis and Design Phase

• Major tasks on the phase of Test Analysis and
  Design
• Reviewing the test basis (such as requirements,
  architecture, design, interfaces)
• Evaluating testability of the test basis and test
  objects
• Identifying and prioritizing test conditions
  based on analysis of test items, the
  specification, behavior and structure
• Designing and prioritizing test cases
• Identifying necessary test data to support the
  test conditions and test cases
• Designing the test environment set-up and
  identifying any required infrastructure and tools
• Creating bi-directional traceability between test
  basis and test cases

Test Design Specification

• Test Design Specification
• It is a document that describes features to be
  tested and specifies list of all test scenarios
  or test cases, which should be designed for
  providing the testing of software
• The test design does not record the values to be
  entered for a test, but describes the
  requirements for defining those values

The objective of compiling test design
specifications is to identify set of features or
a combination of features to be tested and to
identify the group of test cases that will
adequately test those features. In addition to
these it contains all types of refinements done
to the approach described in the test plan.

Test Design Techniques
Testing Design Techniques these are the
techniques that help to derive test cases from
the test basis based on the specifics of the
system under test
The purpose of Test Design Techniques is to
identify test conditions and test scenarios
through which effective and efficient test cases
can be written. Using Test Design Techniques is a
best approach rather the test cases picking out
of the air. Test Design Techniques help in
achieving high test coverage.

Test Design Techniques
Static The fundamental objective of static
testing is to improve the quality of software
work products by assisting engineers to recognize
and fix their own defects early in the software
development.
Dynamic Testing that involves the execution of
the software of a component or system.
