grails-revolver is a Grails plugin for a little more efficient development. The plugin name is inspired by sbt-revolver.

Basically, it tries to minimize impact from Grails minimum-20-sec-startup-time by invoking any grails script reusing existing application context.

#Installation Add plugin in your BuildConfig.groovy:

test ":grails-revolver:0.3.0"

#Usage Well, it is able to run any Grails script, but the script itself should not load Grails application, if it is loaded already:

grails.plugins.revolver.GrailsRevolver.run("test-app integration:")

Unfortunatelly, the 'test-app' command will not work this way, so for that there is a 're-test-app' script, which supports it. From within "grails shell" invoke the following:

grails.plugins.revolver.GrailsRevolver.run("re-test-app integration: org.my.company.MyFavouriteSpec")
// same as
grails.plugins.revolver.GrailsRevolver.testApp("integration: org.my.company.MyFavouriteSpec")

Which will not load a new Grails application from scratch, but reuse same loaded application.

Also you can directly use the 're-test-app':

grails test re-test-app integration: org.my.company.MyFavouriteSpec

Which will rerun tests every time Grails detects changes in any source files.
