Code Coverage Perspective
You can use the Code Coverage perspective to analyze the code coverage results from builds and test runs.
Note
In order to use perspectives with the Team Foundation cube, you must use Microsoft SQL Server 2005 Enterprise Edition or SQL Server 2005 Enterprise (64) Edition on the data tier. SQL Server 2005 Standard Edition that ships as part of Team Foundation Server, does not support the use of perspectives. When you use SQL Server 2005 Standard Edition, the cube elements from all perspectives reside in the Team System data cube.
You can use the code coverage perspective to answer the following types of questions:
Which assemblies and projects have the lowest code coverage?
Which test runs give you the most code coverage?
Which builds have the highest code coverage?
Which architectures or build types have the highest code coverage?
Measures
The following table describes the measures that are included in the Code Coverage perspective. This perspective contains two measure groups: Build Coverage, and Run Coverage. The Build Coverage measures should always be used to analyze numbers summarized by build. The measures in the build coverage measure group do not aggregate across multiple builds to return meaningful numbers. For example, if 100 lines are covered in build 1, and 100 lines are covered in build 2, the total coverage may be far less than 200. The same is true for using run coverage that only returns meaningful numbers when filtered or summarized by a test run.
Measure |
Measure Group |
Description |
|---|---|---|
Count |
Code Coverage from Build |
The number of builds that have code coverage statistics associated with them. |
Lines Covered |
Code Coverage from Build |
The number of lines covered in the selected build. If multiple runs are performed against a build, the build coverage reflects the combined coverage of the runs, taking into consideration that there may be overlap in the lines covered across the runs. |
Lines Not Covered |
Code Coverage from Build |
The number of lines not covered in the selected build. If multiple runs are performed against a build, the build coverage reflects the combined coverage of the runs, taking into consideration that there may be overlap in the lines covered across the runs. |
Lines Partially Covered |
Code Coverage from Build |
The number of lines partially covered in the selected build. If multiple runs are performed against a build, the build coverage reflects the combined coverage of the runs, taking into consideration that there may be overlap in the lines covered across the runs. |
Blocks Covered |
Code Coverage from Build |
The number of blocks covered in the selected build. If multiple runs are performed against a build, the build coverage reflects the combined coverage of the runs, taking into consideration that there may be overlap in the blocks covered across the runs. |
Blocks Not Covered |
Code Coverage from Build |
The number of blocks not covered in the selected build. If multiple runs are performed against a build, the build coverage reflects the combined coverage of the runs, taking into consideration that there may be overlap in the blocks covered across the runs. |
Count |
Code Coverage from Run |
The number of test runs that have code coverage statistics associated with them. |
Lines Covered |
Code Coverage from Run |
The number of lines covered by all tests in a run, taking into consideration that there may be overlap in the coverage across the tests. |
Lines Not Covered |
Code Coverage from Run |
The number of lines not covered by all tests in a run, taking into consideration that there may be overlap in the coverage across the tests. |
Lines Partially Covered |
Code Coverage from Run |
The number of lines partially covered by all tests in a run, taking into consideration that there may be overlap in the coverage across the tests. |
Blocks Covered |
Code Coverage from Run |
The number of blocks covered by all tests in a run, taking into consideration that there may be overlap in the coverage across the tests. |
Blocks Not Covered |
Code Coverage from Run |
The number of blocks not covered by all tests in a run, taking into consideration that there may be overlap in the coverage across the tests. |
Dimensions
The following table describes the attributes that are included in the Code Coverage from the Build perspective. You can aggregate the measures along each of these attributes.
Attribute |
Dimension |
Description |
|---|---|---|
Date |
Date |
The date on which the Run or Build coverage statistics were collected. This dimension should be used together with builds or runs to show the date of a specific build or run. Aggregating coverage measures, if there are no builds or runs, will not consider overlapping code coverage. |
Build |
Build |
Number or name used to uniquely identify the build. |
Build Type |
Build |
Name of the build definition. For more information, see How to: Create a Build Definition. |
Build Start Time |
Build |
Date and time the build began. |
Team Project |
Team Project |
The project against which the coverage statistics were published. |
Platform |
Platform |
|
Build Flavor |
Flavor |
The configuration of the build. For more information, see How to: Create a Build Definition. |
Run |
Run |
The test run ID that was used in generating Run Coverage statistics. |
Remote Run |
Run |
A True/False flag that indicates whether the test run that generated the coverage statistics was a remote test run. |
Assembly |
Assembly |
The assembly name against which the coverage statistics were generated. |
