I have a Groovy DataSource with the following script.  The script does not perform as one would expect.  Instead each call to readLine() reads a line at some random spot way down the file (assuming the file is large enough).  The expected result would be the first line, then the second, etc.

Could this be an issue with Groovy?  Or something else?

The work around is to say "readLines()" and store the result in context.  However, for large files this uses alot of memory.


// Read values from a text file.

if(context["peach"] == null)
{
   context["peach"] = new File("c:/strings.txt").newInputStream()
}

result["value1"] = context["peach"].readLine()

// end

From the GroovyDataSource pane just hit the run button and say 10 iterations and look at the values produced.  The text file would have lines line:

string1
string2
string3
...

So one would expect the values displayed to be string1, string2, ... but instead you get string1 then string1000 or something.  Very strange.

Interesting, that did work.  Wonder why...
