## Regression test ##
A regression tool for QA is build into ResInsight. This tool will read a project file, open all views in this project, save snapshot images to file, and close the project. When snapshot images from all projects are completed, difference images based o generated and QA-approved images are computed. Based on these three sets of images, an HTML report is created and automatically displayed.

### Regression test folder structure ###

```
MyRegressionTestFolder
  TestCase_Faults
    RegTestBaseImages
    RegTestDiffImages
    RegTestGeneratedImages
  TestCase_SOIL
    RegTestBaseImages
    RegTestDiffImages
    RegTestGeneratedImages
  ...
```

### -regressiontest <folder> ###
Run a regression test on all sub-folders starting with ``` TestCase* ``` of the given folder. **RegressionTest.rip** files in the sub-folders will be opened and snapshots of all the views is written to the sub-sub-folder **RegTestGeneratedImages**. Then difference images is generated in the sub-sub-folder **RegTestDiffImages** based 
on the images in sub-sub-folder **RegTestBaseImages**. The results are presented in **ResInsightRegressionTestReport.html** that is written in the given folder.

### -updateregressiontestbase <folder> ###
For all sub-folders starting with ```TestCase*```Copy the images in the sub-sub-folder **RegTestGeneratedImages** to the sub-sub-folder **RegTestBaseImages** after deleting **RegTestBaseImages** completely.
