                                                     HTTP Codes in Testing
As a Performance tester, I always get to see http code in my response tab. Trust me , if we know about it , then it becomes easy in debugging. Today in this post, I will share information on HTTP Codes.

There are 4 main or board categories in HTTP Codes.

è 1xx- Informational
è 2xx- Success
è 3xx- Redirection
è 4xx- Client Error
è 5xx- Server Error

Now let’s move to understand about various possible HTTP code along with its meaning as we received :

è 1xx- Informational
This category of http code tells us about an interim response for communicating connection status or request progress prior to completing the requested action and sending a final response.
These are codes which come under this category:
100: Continue
101: Switching Protocols
102: Processing

è 2xx- Success
These status codes indicate that the client’s request was successfully received, understood, and accepted.
Below are varieties:

 No Authoritative Info
208
 Already Accepted
204
 No Content
226
 IM Used
è 3xx- Redirection
The 3xx (Redirection) class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request.

308
Permanent Redirect

è 4xx- Client Error
This one indicates that the client seems to have errored.
This one is important one so let’s understand the common error we received due to scripting part/Tool part
400 (Bad Request): indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax).
401 Unauthorized: indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.
403 Forbidden: indicates that the server understood the request but refuses to authorize it.
404 Not Found: indicates that the origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
405 Method Not Allowed: indicates that the method received in the request-line is known by the origin server but not supported by the target resource.
415 Unsupported Media Type: indicates that the origin server is refusing to service the request because the payload is in a format not supported by this method on the target resource. The format problem might be due to the request’s indicated Content-Type or Content-Encoding, or as a result of inspecting the data directly.

è 5xx- Server Error
Again, this type http code is very important because this is what we look for. One of the purposes of testing to uncover these codes and get them fixed by team.
The 5xx (Server Error) class of status code indicates that the server is aware that it has erred or is incapable of performing the requested method.
500 Internal Server Error: indicates that the server encountered an unexpected condition that prevented it from fulfilling the request.
502 Bad Gateway: indicates that the server while acting as a gateway or proxy, received an invalid response from an inbound server it accessed while attempting to fulfill the request.
503 Service Unavailable: indicates that the server is currently unable to handle the request due to a temporary overload or scheduled maintenance, which will likely be alleviated after some delay.
504 Gateway Timeout: indicates that the server while acting as a gateway or proxy, did not receive a timely response from an upstream server it needed to access in order to complete the request

Pacing Calculation in Load runner

By
                                        Today i will share my understanding on “Pacing”. Usually people take pacing as think time only. I will try to explain both terms first Think time and Pacing, both are a kind of “wait” or “delay” in terms of time but still both differ from each other. Think time: Think Time is the time or delay which user can take between two actions For example, User opens a URL by pressing “Enter” and login page appears but to enter user name or password user is taking some time like copying from other place or remembering it or something like that. This wait or delay we can term as think time in load runner. Think time can be inserted by user in script or captured by tool itself Whereas, Pacing is the delay between two iterations of test. We can give pacing time by using “Runtime Settings” of load runner tool. We can calculate Pacing/Think...

MI Listener in LoadRunner

By
In a regular LoadRunner load test scenario (not over a firewall), The Controller has direct access to the LoadRunner agents running on remote machines. This enables the Controller to connect directly to those machines. When running Vusers or monitoring applications over a firewall, this direct connection is blocked by the firewall. The connection cannot be established by the Controller, because it does not have permissions to open the firewall. LoadRunner solves this problem by using a communication configuration based on HTTPS or secured TCP/IP. This configuration uses the standard SSL port on the firewall (port 443). The MI Listener is a component that serves as router between the Controller and the LoadRunner agent. When the LoadRunner agent connects to the MI Listener, the MI Listener keeps a listing of the connection to the agent using a symbolic name that the agent passed to it. When the Controller connects to the MI Listener, it communicates to the MI Li...

Mobile Web(Http/HTML) Protocol IN Loadrunner

By
Today i will share my learning on performance testing performed on mobile application. We can use Load runner tool for mobile based applications. HP LoadRunner 11.50 has two new protocols for helping to record mobile applications: ·          Mobile Application – HTTP/HTML : recording scripts at the transport level for both browser-based mobile applications and native mobile applications, that communicate with their servers over HTTP ·          Mobile TruClient: recording scripts for browser-based mobile applications through the browser-based user interface.  This protocol is based on Ajax TruClient, using a browser modified to emulate the mobile browser. These protocols are independent of mobile operating systems, so will work on different versions of iOS, Android, Windows Mobile, WebOs (Palm), Blackberry, etc. Let’s see the picture behind the scene: We can run the p...

Performance Testing of Documentum

By
Before starting details of how to do performance testing on Documentum I will try share a basic of Documentum so you can get an idea why we need a different approach while doing performance testing on it. What is Documentum? Documentum is content management software that provides management of document content and attributes. Documentum product is a three-tier, client-server system built on top of a relational database. Documentum components comprise the following: ·          Content Server - Manage access to the metadata stored in the relational database and the  Content files, usually stored in the file system ·          Webtop/Wdk Server - J2EE-based web application framework Behavior behind the scene: An applet is invoked at the client side when a file within the docbase is accessed and while files are imported into a docbase. Applet/UCF client being client side Java applic...

CITRIX Error in Load runner: Failed to get window size, wrong format.

By
Citrix based Applications are now days very popular. We can perform load testing on Citrix based application using load runner tool also. Quick tips for Citrix applications: 1. You can use "HTTP" and "Citirix" protocol together in load runner. 2. Try to keep windows in full screen mode. Some time while replaying the recorded script can give some error too. one of the error i have encountered was: Error: Failed to get window size, wrong format. Unable to detect client version. Warning: Extension CitrixClientImpl.dll reports error -1 on call to function ExtPerThreadInitialize Error: Vuser failed to initialize extension CitrixClientImpl.dll Resolve the issue: 1. Save the script after recording. 2. Go to Script directory and look for "default.cfg” file 3. Open the file into edit mode 4.

Heap Dump : how to generate heap dump

By
Heap dump is important when it’s come to performance testing. Let’s start with what is heap in an application. Heap: Heap is dynamically collective amount of data /memory in partially binary sorted tree structure. But we need to loop up on heap in term of memory. Heap is part of memory where memory for objects assigned dynamically. Heap dump : Heap Dump is snapshot of memory at certain point which contains below mentioned information: -information of java objects -information of java classes or we can define as A heap dump is a textual or binary representation of the Java heap which is usually written to a file.   Heap dump is always helpful to analyze memory leak or high usage of memory of java application. There are various tools which help us to generate the heap dump. We can also generate heap dump without using tools. What we require is JVM (Java Virtual Machine)on system. There are various vendors for JVM but let’s concentrate on Sun JVM. ...

Record scripts on mobile applications in LoadRunner

By
Record scripts on mobile applications in LoadRunner : As LoadRunner 11 in Patch 3, Mobile App (HTTP/HTML) protocol added which can help us to record scripts of mobile apps. There are three recording options in the recording Wizard: 1.Record and Analyze Traffic - Use mobile sniffer agent to capture traffic and then analyze. This allows Vugen to connect to the mobile agent on the server or localhost and carry out the business process for recording. 2. Analyze Traffic - Analyze traffic using existing capture file to generate script. This allows Vugen to scan a pre-captured network traffic (WinPcap) file and generate the code based on the traffic. 3. Record Emulator - Record script using a mobile device emulator. This allows Vugen to record an emulator installed on the Vugen machine. With this option, you need to verify that you are able to bring up the emulator and navigate to a URL outside of Vugen to make sure the emulator settings are correct.
