Use these patterns together with CaptureFD and EXPECT_PCRE_MATCH() to test for the presence (or absence) of log lines at a particular level:

Synopsis

Declared in <folly/testing/TestUtil.h>

std::string

Description

CaptureFD stderr(2); LOG(INFO) << "All is well"; EXPECT_NO_PCRE_MATCH(glogErrOrWarnPattern(), stderr.readIncremental()); LOG(ERROR) << "Uh-oh"; EXPECT_PCRE_MATCH(glogErrorPattern(), stderr.readIncremental());

Return Value

A PCRE pattern matching an error-level glog line.
