the assertion is satisfied. If the types are different, the function call will
fail to compile, the compiler error message will say that
`T1 and T2 are not the same type` and most likely (depending on the compiler)
show you the actual values of `T1` and `T2`. This is mainly useful inside
template code.

## Using Assertions in Sub-routines
{: .callout .note}
Note: If you want to put a series of test assertions in a subroutine to check
for a complex condition, consider using
[a custom GMock matcher](gmock_cook_book.md#NewMatchers)
instead. This lets you provide a more readable error message in case of failure
and avoid all of the issues described below.

#### Detecting Test Premature Exit
Google Test implements the _premature-exit-file_ protocol for test runners
to catch any kind of unexpected exits of test programs. Upon start,
Google Test creates the file which will be automatically deleted after
all work has been finished. Then, the test runner can check if this file
exists. In case the file remains undeleted, the inspected test has exited
prematurely.
