I've seen some test use just `// break` instead of `// break here`. Having the ability to optionally specify a pattern or file would be nice:

```suggestion
    def build_and_run(self, dictionary=None, file=None, pattern=None):
        """
        Builds the target binary, launches it and runs to the breakpoint
        location specified by the '// break' comment.
        """
        self.build(dictionary=dictionary)
        
        if not pattern:
            pattern = "// break "

        if os.path.exists(file):
            lldbutil.run_to_source_breakpoint(
                self, pattern, lldb.SBFileSpec(file, False)
            )
                        
        main_candidates = ["main.c", "main.cpp", "main.m", "main.mm" ]

        for candidate in main_candidates:
            if os.path.exists(candidate):
                lldbutil.run_to_source_breakpoint(
                    self, pattern, lldb.SBFileSpec(candidate, False)
                )
```
