How to automate soap ui projects to run all the project in one click

You can execute all test cases from your worspace by the following Groovy script:

import com.eviware.soapui.model.testsuite.*
import com.eviware.soapui.support.types.StringToObjectMap
import com.eviware.soapui.SoapUI

project = testRunner.getTestCase().getTestSuite().getProject().getWorkspace().getProjectByName("Project1")

for(project in SoapUI.workspace.projectList) {    
  log.info project.getName()

  project.getTestSuiteList().each {
	TestSuite ts = it
	List<TestCase> tcs = ts.getTestCaseList()
	tcs.each {
		TestCase tc = it
		log.info "Running " + project.getName() + " " + tc.getName()
		tc.run(new StringToObjectMap(), false)
	}
  }
 }
 

You can modify the script to choose the suits, test cases etc.

You can execute the script e.g. if you create a new project/test suite/test case and define a Groovy script test step. Then you launch this step to execute the script, just avoid the infinite loop.
