Test Management

Organisation - organisational structures for testing; team composition
Explain that organisations may have different testing structures: testing may be the developer’s responsibility, or may be the team’s responsibility (buddy testing), or one person on the team is the tester, or there is a dedicated test team (who do no development), or there are internal test consultants providing advice to projects, or a separate organisation does the testing.

A multi-disciplinary team with specialist skills is usually needed. Most of the following roles are required: test analysts to prepare strategies and plans, test automation experts, database administrator or designer, user interface experts, test environment management, etc.

Configuration Management
Describe typical symptoms of poor CM such as: unable to match source and object code, unable to identify which version of a compiler generated the object code, unable to identify the source code changes made in a particular version of the software, simultaneous changes are made to the same source code by multiple developers (and changes lost), etc.

Configuration identification requires that all configuration items (CI) and their versions in the test system are known. Configuration control is maintenance of the CIs in a library and maintenance of records on how CIs change over time.

Status accounting is the function recording and tracking problem reports, change requests, etc.
Explain that configuration auditing is the function to check on the contents of libraries, etc. for standards compliance, for instance.

CM can be very complicated in environments where mixed hardware and software platforms are being used, but sophisticated cross-platform CM tools are increasingly available.

Test Estimation, Monitoring and Control

Test estimation - explain that the effort required to perform activities specified in the high-level test plan must be calculated in advance and that rework must be planned for.

Test monitoring – describe useful measures for tracking progress (e.g. number of tests run, tests passed/failed, incidents raised and fixed, retests, etc.). Explain that the test manager may have to report on deviations from the project/test plans such as running out of time before completion criteria achieved.

Test control – explain that the re-allocation of resources may be necessary, such as
changes to the test schedule, test environments, number of testers, etc.

Incident Management

An incident is any significant, unplanned event that occurs during testing that requires subsequent investigation and/or correction. Incidents are raised when expected and actual test results differ.

Incidents may be raised against documentation as well as code or a system under test.

Incidents may be analysed to monitor the test process and to aid in test process improvement.

Incidents should be logged when someone other than the author of the product under test performs the testing. Typically the information logged on an incident will include expected and actual results, test environment, software under test id, name of tester(s), severity, scope, priority and any other information deemed relevant to reproducing and fixing the potential fault.

Incidents should be tracked from inception through various stages to eventually close out and resolution.
