I started Sailfish as follows:

1. git clone https://github.com/exactpro/sailfish-core.git
2. cd sailfish-core
3. ./gradlew clean build -x test
4. ./gradlew cleanSharedWorkspace publishPlugin
5. ./gradlew cargoRunLocal -PquickStart

Hi, @mbolotov. Currently MatrixEditor (Edit in grid) is not considered as test scripts IDE. It supposed to be used for adhoc edits or something like that.

You can refer to the attached examples. There are two services to be imported on Environment tab and csv matrix to be uploaded on Test scripts tab in the zip.
