Hello.

How ar eyou doing today?

Maybe you can try to help me with one issue. I have Apex Class - EmployeeMonthlyEmail, which takes collection of employees, and sends them emails. And another Test Apex Class - TestEmployeeMonthlyEmail for code coverage. Unfortunately, code coverage is 0%, and I am unable to understand why.

Please see code below. Based on test run results, situations with Good and Bad emails provided to a function are covered, and tests finish correctly returning True/False as expected. However, Code Coverage is at 0% and 0/27 lines.

Here is a screen shot with code coverage info and test run:

Please note that during debug execution, code works as expected and emails are received on GMail account. It means code is written corretly, but Code Coverage probably is done inappropriately.

Any ideas what is wrong in this situation?

p.s. TestDataFactory class works as expected - generates records, previously test code did not use DataFactory and code coverage was also 0%

Caused the following Apex resource warnings:

Approaching limit for non-selective query against large object type (more than 100000 rows). Current size is approximately 76265 rows. When the limit is reached, the query will fail. Consider an indexed filter or contact salesforce.com about custom indexing.
Even if a field is indexed a filter might still not be selective when:
1. The filter value includes null (for instance binding with a list that contains null)
2. Data skew exists whereby the number of matching rows is very large (for instance, filtering for a particular foreign key value that occurs many times)
