Description
This is useful for looking for patterns in logging files that can grow quite large.
This is taken from code from 

    /**
     * Verify that the contents of the file contains the given the set of strings
     *
     * @param file File to check for expectedStrings
     * @param expectedStrings Strings that file should contain
     * @throws RuntimeException If the string was not found
     * @throws IOException If the file cannot be opened
     */
    public OutputAnalyzer shouldContain(File file, String ... expectedStrings) throws IOException {
Comments
import java.nio.file.Files; ... OutputAnalyzer fileContents = new OutputAnalyzer(Files.readString(<file Path>)); So no need for a new API unless you want to add a shouldContain(String ... expected) to process multiple strings.

OutputAnalyzer can be created using a process, from which the output streams are extracted and the contents analyzed; or from a String (which is presumed to be the captured output of a process), so a natural extension to that could be to create one using a File that contains the process output. Though you can also convert a file's contents into a String and use the existing OutputAnalyzer(String) constructor. I don't think an instance method, shouldContain, that takes a file and only operates on that file makes sense for OutputAnalyzer.
