Detailed Description

Runs a variety of checks to make sure the histogram in the input filename is what we expect it to be.

Does NOT check that the entries in the histogram are correct, just makes sure that there is the correct number.

Does check:

• The input file name is readable
• The input file has the directory "TestAnalyzer"
• The directory has the histogram "test_hist_"
• The histogram has the correct number of entries

Describe this matcher in a helpful, human-readable way.

This string is written as if stating a fact about the object it is matching.

match()

bool framework::test::isGoodHistogramFile::match ( const std::string &  filename ) const

inlineoverride

Performs the test for this matcher.

Opens up the histogram file and makes sure of a few things.

• The histogram 'test_hist_' is in the 'TestAnalyzer' directory
• The histogram has the correct number of entries

Definition at line 193 of file FunctionalCoreTest.cxx.

                                                       {
    // Open file
    TFile* f = TFile::Open(filename.c_str());
    if (!f) return false;
    TDirectory* d = (TDirectory*)f->Get("TestAnalyzer");
    if (!d) return false;
    TH1F* h = (TH1F*)d->Get("test_hist_");
    if (!h) return false;
 
    return (h->GetEntries() == correctGetEntries_);
