What does TDR mean in NASA

A Test Discrepancy Report (TDR) is used to track potential defects or issues in the software development and testing process. It documents the inconsistencies between the expected result of a test and the actual result, providing stakeholders with an overview of potential areas for improvement.

Tracking discrepancies in tests is an important part of the software development cycle, as it allows developers to identify issues quickly and accurately and make any necessary changes to ensure that code meets quality standards. Without accurate tracking, developers may miss critical errors which can lead to costly mistakes down the line.

A TDR functions by documenting any discrepancies between specific requirements and their outcomes in any given test case. This includes documenting any failures, unexpected results, or information about the root cause of the issue or defect. This information can then be used to help identify ways to improve the software before release.

A TDR should include clear details regarding each discrepancy encountered during testing such as screenshots of any errors, descriptions of problems encountered, data on how long it took for errors to occur, timestamp of when tests were run, and URLS associated with related items or external concerns. Additionally, any information related to mitigating factors or other relevant data around how tests were conducted should also be included.

The responsibility for creating a TDR usually falls on Quality Assurance (QA) teams and engineers who are conducting tests and evaluating bug reports. Those teams/individuals will document all discrepancies encountered throughout testing processes as well as resolutions taken or suggested measures for improvement.

Best practices when compiling a TDR include ensuring that all reported discrepancies provide detail about what actions led up to failure state within each test case; reporting on consistently across different tests; double-checking results before submitting reports; using clear language that other stakeholders can understand; making sure there's enough information provided so that developers can take action when needed; including reference material such as relevant URLs; describing actual impacts instead of just talking about symptoms.

One way to streamline creating TDRs is through automation tools such as Selenium Test Automation Framework which can automatically generate comprehensive reports at each step of the testing process without requiring manual input from testers or developers. This reduces time spent on creating individual reports and makes it easier for stakeholders review trends in report results more efficiently.

Test Discrepancy Reports should be reviewed by both testers and developers alike in order to ensure that all issues are addressed quickly and efficiently. Reviewing these reports helps ensure quality assurance standards are being met while also providing feedback which can help find opportunities for improvement.

Accessibility depends on team size and organizational structure but typically those with editing permissions would include product owners, QA engineers/leads & project managers along with others involved in maintaining quality assurance standards within software development projects.

It’s recommended that you review your Test Discrepancy Reports regularly - ideally after completing testing cycles but no less than once every two weeks - so that you have an overview of current status against planned objectives as well as any trends across previous tests.
