How to use resources

Jython and generic Groovy

Some users want to use txt or xml files to externalize the resources from scripts. For example, if you have a bunch of user ids and need to test some system with those ids, keeping all ids in the script is not realistic. Instead, you can use resources files which nGrinder supports. Only following file type are distributable

• json, csv, txt, properties

To use resources files, you can create resources folder at the same location with the script.

The resources folder containing multiple resource files will be passed to the agents during the test execution. In the script you can refer the these resources  like following code.

Jython

from net.grinder.script import Test
from net.grinder.script.Grinder import grinder
from net.grinder.plugin.http import HTTPRequest                                                             

test1 = Test(1, "Test1")
test_host = "http://www.sample.com"
request1 = test1.wrap(HTTPRequest(url=test_host))

test_query_file = "./resources/rows_10.txt"


class TestRunner:
    def __init__(self):
        self.urlCount = 0
        self.urlList = []
        
        try:
            fpQuery = open(test_query_file, "r") 
            ....

Generic Groovy

String text
	@BeforeThread
	public void beforeThread() {
		grinder.statistics.delayReports=true;
		grinder.logger.info("before thread.");
		text = new File("./resources/resource1.txt").text;
	}
	
	
	@Test
	public void test(){
		println(text)
		HTTPResponse result = request.GET("http://www.google.com");
		if (result.statusCode == 301 || result.statusCode == 302) {
			grinder.logger.warn("Warning. The response may not be correct. The response code was {}.", result.statusCode);
		} else {
			assertThat(result.statusCode, is(200));
		}
	}

Groovy Maven Project

import org.codehaus.groovy.reflection.ReflectionUtils;
....
 
 
class YourTest {
    String text;
 
    @BeforeThread
    public void beforeThread() {
       // In groovy, InputStream contains text field.
       text = loadResourceFromClassPath("/resource1.txt").text;
    }
 
    @Test
    public void doTest() {
       ....
    }
 
    // This is groovy way to load resource from classpath
    public loadResourceFromClassPath(String resourcePath) {
        return ReflectionUtils.getCallingClass(0).getResourceAsStream(resourcePath);
    }
}
