![]() ![]() ![]() Adding page assertions will be validating the page is a valid response or not. VuGen is generally used to record user flow and enhance them to work for multiple users and add dynamic data as input using parameterized and correlation to support multiple users. These 3 components are used to do end-to-end testing. LoadRunner has 3 components which are Vugen, Controller, and Analysis. How to Add External Jars in LoadRunner Java Vuser Scripts LR supports almost all types of protocols like Mobile, Web, Database, Java, Web sockets, etc, performance testing. This is how the JavaScript code within the BSF assertion could look like: //Get the jMeter variable and put it in a Javascript variable var password = vars.get(âPASSWORDâ) //the actual magic: the calling of a Java class function from within JavaScript //This is not an actual password encryption, only an example by help of a jMeter class available //You can find this class in ~jmeter/lib/soap.jar var hashedpassword = .Utils.cleanString(password) //Put the result back into a jMeter variable for further processing vars.put(âHASHEDPASSWORDâ,hashedpassword) //and since weâre not testing anything in this âBSF assertionâ, we will always call it a success: tFailure(false) įull example, tested with Jmeter 2.3.2 (copy this into a test.jmx text file): false false false 1 1 0 1230116483000 1230116483000 false stoptest PASSWORD = HASHEDPASSWORD ThisShouldBeGoneWIthTheSecondHTTPRequest = http / GET false true true false false //Get the jMeter variable and put it in a Javascript variable var password = vars.get('PASSWORD') //the actual magic: the calling of a Java class function from within JavaScript //This is not an actual password encryption, only an example by help of a jMeter class available //You can find this class in ~jmeter/lib/soap.jar var hashedpassword = .Utils.cleanString(password) //Put the result back into a jMeter variable for further processing vars.put('HASHEDPASSWORD',hashedpassword) //and since we're not testing anything in this 'BSF assertion', we will always call it a success: AssertionResult.How to Add External Jars in LoadRunner Java Vuser Scripts: LoadRunner is one most popular licensed performance testing tools, LoadRunner is acquired and managed by Micro Focus company.![]() Put âjavascriptâ in the âscript languageâ field of the BSF assertion.Add the âBSF samplerâ to the HTTP request sampler containing the username/password login page.Add a âuser definded variableâ test component, and add a field called âPASSWORDâ with variable âsecretâ, and an empty field âHASHEDPASSWORDâ.download the websiteâs JAR file, and put it in the jMeter java classpath.by using a class file to encrypt a username/password combination by using a custom java function: ![]() Using this function from within JavaScript is can be done by calling the function with itâs full path, and by adding âPackages.â in front of it.Ä®xample java class function use within jMeter, e.g. If you have a custom class in a JAR file provided by the website, the regular path to that class would be, and the function can be called âFunctionNameâ. And hereâs the trick: JavaScript provides a bridging function towards java libraries, via the Packages method. Hereâs the trick: JavaScript provides a bridging function towards java libraries, via the Packages method.Ä«ut jMeter does support a way to execute JavaScript functions, via the âBSF assertionâ. JMeter does not process Javascript or applets embedded in HTML pages.â. There I was, with a need for executing a custom java class, and a clear FAQ on the jMeter site telling me explicitely âDoes JMeter process dynamic pages (e.g. In one of my last assignments to benchmark a site, the site turned out to use java classes, with browser-based functions to create an encrypted password which in turn was sent to the web site for authentication. Iâd rather have a slow web site where 8 web servers are running at 95% cpu, than a collapsed farm because end-users hit the F5 button after receiving a system error. My ultimate goal is not to find the moment where the site breaks, but to tune the site to a level where it actually never breaks, but only becoming slow, without collapsing via some snowball effect on system resources. Itâs funny to see how a site behaves (or dies) when the system is running out of resources. I use it to see how much end-users can log in to their banking environment and check their current account details, to validate how much inserts/sec can be handled by a database, the maximum amount of ldap lookups, etc.Äuring testing, the most interesting things usually happen during the load test. JMeter is a great tool to perform several load and stress tests on websites, ftp servers, database servers and more. ![]()
