While deploying non apex component if testLevel is set to "RunSpecifiedTests" then deployment fails if any Trigger has less than 1% code coverage

Fixed - Winter '16

Summary
In summer 15 release ,the "runAllTests" deployment option is now replaced with "testLevel". Test levels enable you to have more control over which tests are run in a deployment. The default Test Execution in Production has changed ,When no test level is specified in the deployment options, the default test execution behavior depends on the contents of your deployment package.
- When deploying to production, all tests, except those that originate from managed packages, are executed if your deployment package contains Apex classes or triggers.
- If your package doesn’t contain Apex components, no tests are run by default.

But if you are not deploying any apex component and still want to run specific test classes in <runTest> tag while using "RunSpecifiedTests" for testLevel, then deployment fails if any trigger has less than 1% code coverage for both WorkBench and Force.com Migration Tool

PLEASE NOTE- When there are apex components in the deployment package and using testLevel="RunSpecifiedTests" and <runTest> tag specify test classes , deployment is successful even if any trigger has less than 1% code coverage , if that trigger test class is not specified in the <runtest> option , so please check your code coverage if you get this error.

Repro
Example- The destination org has one trigger (LeadHtmlError) which has no code coverage and deployment package only contains profiles.

Actual Results
------------------
BUILD FAILED
C:\Users\<user>\Documents\migration tool\sample\build.xml:98:
*********** DEPLOYMENT FAILED ***********
Request ID: 0AfM0000009UDOgKAO

Code Coverage Failures:
1. Class: LeadHtmlError -- Test coverage of selected Apex Trigger is
0%, at least 1% test coverage is required
*********** DEPLOYMENT FAILED ***********


Expected behaviour
-------------------
RunSpecifiedTests—Only the tests that you specify in the runTests option are run. Code coverage requirements differ from the default coverage requirements when using this test level. Each class and trigger in the deployment package must be covered by the executed tests for a minimum of 75% code coverage. This coverage is computed for each class and trigger individually and is different than the overall coverage percentage
as there were no apex component so no code coverage should be in-forced.

Workaround
1) For deploying production org

<target name="deployCodenonapexcompwithtest">
<sf:deploy username="${sf.username}" password="${sf.password}" serverurl="${sf.serverurl}" deployRoot="nonapexcomp" checkOnly="true>
</sf:deploy>
</target>

2) For Sandbox production org

<target name="deployCodenotest">
<sf:deploy username="${sf.username}" password="${sf.password}" serverurl="${sf.serverurl}" deployRoot="nonapexcomp" checkOnly="true" testLevel="NoTestRun">
</sf:deploy>
</target>
