Overview

In this article, we will discuss the Test Plan document. A Test Plan is a formal document that describes

Test planning is influenced by the test policy of an organization, the scope of testing, objectives, risks, constraints, criticality, testability, and the availability of resources.

It is a continuous activity & is performed throughout all project processes & activities. Feedback gathered from test activities is used to recognize changing risks & planning is enhanced accordingly.

Test Planning Activities

Defining the test strategy, including the definition of all test levels, entry/exit criteria
Integration & coordination of testing activities software life cycle activities
Critical decisions like what to test, defining roles to be  performed, when & how the testing activities should take place, how to evaluate the test results & most importantly when to stop testing (exit criteria)
Selections & assignment of resources for various roles identified.
Selecting metrics for monitoring test preparation & execution, defect resolutions & risks

Test Approaches

Mostly test approach strategies can be 2 ways.
Preventive Approach: Tests are designed as early as possible in the cycle.
Reactive Approach: Test Design starts after the software system has been produced.

Test Exit Criteria

The purpose of exit criteria is to define goals that should enable the management to decide on whether to stop the testing or not.

Examples of sample exit criteria :
The thoroughness with regards to code coverage, functionality, or Risk
Estimates of defect density or reliability measures
3.Cost & time factors

Test Estimation

Approaches for estimation :

Estimating the testing efforts based on metrics of former or similar projects.

Estimating of the tasks by the owner of the tasks or by experts

Test Monitoring

Test progress monitoring is the process in which various test activities are assessed & compared against their planned goals. Metrics can be used to measure the progress of various activities.
Percentage of work done in test case preparation
Percentage of work done in test environment preparation
Test case execution (e.g. no of test cases run/not run, test cases passed/failed)
Defect Information (Defects found/fixed, failure rate, retest progress)

Test Reporting

Test reporting summarizes information about the following :
Testing progress in terms of test case execution, defects opened, defects fixed, no re-tests occurred, etc.
Metrics to support recommendations & decisions for future actions such as unfixed defects & their impact on the project, outstanding risks, level confidence in the quality of software.
