Can Selenium verify text inside a PDF loaded by the browser?

by

While not natively supported, I have found a couple ways using the java driver. One way is to have the pdf open in your browser (having adobe acrobat installed) and then use keyboard shortcut keys to select all text (CTRL+A), then copy it to the clipboard (CTRL+C) and then you can verify the text in the clipboard. eg:

protected String getLastWindow() {
    return session().getEval("var windowId; for(var x in selenium.browserbot.openedWindows ){windowId=x;} ");
}

@Test
public void testTextInPDF() {
    session().click("link=View PDF");
    String popupName = getLastWindow();
    session().waitForPopUp(popupName, PAGE_LOAD_TIMEOUT);
    session().selectWindow(popupName);

    session().windowMaximize();
    session().windowFocus();
    Thread.sleep(3000);

    session().keyDownNative("17"); // Stands for CTRL key
    session().keyPressNative("65"); // Stands for A "ascii code for A"
    session().keyUpNative("17"); //Releases CTRL key
    Thread.sleep(1000);

    session().keyDownNative("17"); // Stands for CTRL key
    session().keyPressNative("67"); // Stands for C "ascii code for C"
    session().keyUpNative("17"); //Releases CTRL key

    TextTransfer textTransfer = new TextTransfer();
    assertTrue(textTransfer.getClipboardContents().contains("Some text in my pdf"));
}

Another way, still in java, is to download the pdf and then convert the pdf to text with PDFBox, see http://www.prasannatech.net/2009/01/convert-pdf-text-parser-java-api-pdfbox.html for an example on how to do this.
