4 Defect ManagementA major test objective is to identify defects. Once identified, defects need to be recorded, monitored, reported and corrected.The primary goal is to prevent defects.The defect management process like the entire software development process, should be risk driven, i.e., strategies, priorities and resources should be based on an assessment of the risk.Defect measurement should be integrated into the development process and be used by the project team to improve the development processDefect information should be used to improve the processImperfect or flawed processes cause most defects.
5 Defect Management A defect can be defined in one of two ways From the producer’s viewpointA defect is a deviation from specifications, whether missing, wrong, or extraFrom the Customer’s viewpointA defect is anything that causes customer dissatisfaction, whether in the requirements or not; this is know as ”fit for use.”
6 Defect ManagementThe following structure is recommended to report a defect:Title:Type the problem encountered in the application, the title needs to be understandableFor Example:You can use the following categories:MissingInaccurateIncompleteInconsistentIncorrect Example:Missing validation in “Project” fieldIncorrect spelling in “status” drop down list
7 Defect Management Description Type a brief description of the problem Repro Steps:Type all the steps to get to the problem, all steps must be clearedFor example:1.- Login to FIDO2.- Click on Add Invoice3.- Type in Project field4.- Click on Save
8 Defect Management Actual Results Type the actual results of the action For example:The following error message is displayed..Comments:Type any comments or notify to the developers of any screenshots(attachments)For Example: This defect is reproducible in Project field. (see attached file)Expected ResultsType the expected results of the action.For Example:Data should be saved successfully.
9 Defect Management Test Environment Include details of the test environmentFor Example:Microsoft Windows 2003 StandardOffice 2003The following slide shows an example of a complete Defect Report
10 Defect Management Consider the following caveats Most of the organizations have a Defect Tracking Tool to log the defects found during Test Execution, one of the most common tools in the market is Test Director of Mercury toolsThe budget in some organizations is limited to afford buying a commercial tool, thus they prefer to create their own defect tracking processA very simple way to track the defects of the application is using a spreadsheet of ExcelThe following slide shows an example of a complete Defect Report and a Defect Tracking Sheet in Excel
14 Defect Management Process The steps below describe a simple defect tracking process:Execute the test and compare the actual results to the documented expected results.If a discrepancy exists, log the discrepancy with a status of “open”. Supplementary documentation, such as screen prints or program traces, should be attached if available.The test manager or tester should review the problem log with the appropriate member of the development team to determine if the discrepancy is truly a defect.
15 Defect Management Process Assign the defect to a developer for correction.Once the defect is corrected, the developer will usually enter a description of the fix applied and update the defect status to “Fixed” or “Retest”.The defect is routed back to the test team for retesting.Additional regression testing is performed as needed based on the severity and impact of the fix applied.If the retest result match the expected result, the defect status is updated to “closed”. If the test results indicate that the defect is still not fixed, the status is changed to “open” and sent back to the developer.
