Winter '16 - In Developer Console, running tests synchronously does not generate code coverage

Fixed - Spring '16 Patch 2.0

In Winter '16, Salesforce introduced a new option under the 'Test' tab in the Developer Console called 'Always Run Asynchronously'. By default, this option is unchecked which will in turn run tests synchronously.

Presently, in Winter '16 orgs, when we run tests synchronously via the Developer Console, we observe no code coverage is calculated. Further, when we query the objects 'ApexCodeCoverage' and 'ApexCodeCoverageAggregate' via Tooling API, we observe no results for the class being tested.

1. In a Winter '16 org, create a new trigger as follows using any API version:

trigger codeCoverageTrigger on Case (before insert) {

for (Case c:
c.Subject='TEST CASE for code coverage';
c.description = 'Hello World';

2. Create a test class for the trigger to generate code coverage as follows:

public class codeCoverageTrigger_Test{

static testMethod void insertCase()
Case testCase = new Case();
insert testCase ;

3. Open Developer Console and examine the 'Test' tab, observe the option 'Always Run Asynchronously'. In Winter '16 orgs, this option is unchecked by default which will in turn run tests synchronously. For this repro, leave it unchecked.

4. In Developer Console, open the test class 'codeCoverageTrigger_Test' (Developer Console->File->Open->Classes) and click 'Run Test'

5. You can monitor the test run via 'Apex Test Execution' section(Setup->Develop->Apex Test Execution), once complete open the trigger 'codeCoverageTrigger'

6. Observe the code coverage for the trigger is 0%, if we further examine the code coverage breakdown via Developer Console or by querying the objects 'ApexCodeCoverage' and 'ApexCodeCoverageAggregate' via Tooling API, we will observe no coverage is generated for the trigger

In Winter '16 orgs, if we check the option 'Always Run Asynchronously' under the 'Test' tab and re-run the test class via Developer Console, code coverage will be generated as expected.

Alternatively, if the tests are ran via the UI, code coverage is generated as expected.

Is it Fixed?
