A regression tool for QA is build into ResInsight. This tool will do the following:
|
|
|
|
1. Scan a directory for sub directories containing a **RegressionTest.rip** files.
|
|
2. Each found project file will be opened, and all views in this project will be exported as snapshot images to file.
|
|
3. When snapshot images from all projects are completed, difference images based on generated and QA-approved images are computed.
|
|
4. Based on these three sets of images, an HTML report is created and automatically displayed.
|
|
|
|
## Starting regression tests
|
|
|
|
To be able to run regression tests you need the **compare** tool from the [ImageMagic suite](http://www.imagemagick.org/script/compare.php).
|
|
|
|
You can start the tests either from the command line or from the ResInsight Gui.
|
|
From the ResInsight Gui select : **File->Testing->Regression Test Dialog**
|
|
|
|
|
|
|
|
Specify location of compare tool in **Folder containing compare**. The current working directory of ResInsight is temporarily changed to this path during execution.
|
|
|
|
## Creating regression tests
|
|
|
|
An example of the folder structure is shown below:
|
|
|
|
RegressionTestFolder/
|
|
TestCase1/
|
|
RegressionTest.rip
|
|
RegTestBaseImages/
|
|
RegTestDiffImages/
|
|
RegTestGeneratedImages/
|
|
TestCase2/
|
|
...
|
|
|
|
To create regression tests you need to do the following:
|
|
|
|
1. Create a root directory containing one directory for each test case.
|
|
2. In each of the **Test Case** folders create a ResInsight project file called **RegressionTest.rip**.
|
|
3. Run the regression test for the first time, and thereby creating images that can be used as Base images.
|
|
4. Rename the generated RegTestGeneratedImages/ folder to RegTestBaseImages/
|
|
|
|
Now you are all set to test new releases of ResInsight towards your own Regression tests. |
