As I am training myself to Apache JMeter<\/a>, beside testing on my Oracle environment (which include Oracle Internet Directory, Oracle Directory Service Manager, Oracle Identity and Access Management, a Database and a web application protected by SAML), I was looking for a tool to test more feature of it.<\/p>\n\n\n\n

I found a website called httpbin<\/a>. You can find plenty of tools to do online testing, but this one can even be self-hosted within a docker image.<\/p>\n\n\n\n

In this blog, I will explain how to setup httpbin and then use one of this many features to crawl a website to, for example, looking for dead links.<\/p>\n\n\n\n

httpbin<\/h2>\n\n\n\n

Starting httpbin is easy as running this command (and it is not the only advantage of it):<\/p>\n\n\n

\ndocker run -p 80:80 kennethreitz\/httpbin\n<\/pre><\/div>\n\n\n
After pulling the image, the server runs and makes the main web page available:<\/p>\n\n\n\n
\"\"<\/p>\n\n\n\n
It has following features:<\/p>\n\n\n\n
    \n
  • HTTP Methods: Testing different HTTP verbs<\/li>\n\n\n\n
  • Auth: Auth methods<\/li>\n\n\n\n
  • Status codes: Generates responses with given status code<\/li>\n\n\n\n
  • Request inspection: Inspect the request data<\/li>\n\n\n\n
  • Response inspection: Inspect the response data like caching and headers<\/li>\n\n\n\n
  • Response formats: Returns responses in different data formats<\/li>\n\n\n\n
  • Dynamic data: Generates random and dynamic data<\/li>\n\n\n\n
  • Cookies: Creates, reads and deletes Cookies<\/li>\n\n\n\n
  • Images: Returns different image formats<\/li>\n\n\n\n
  • Redirects: Returns different redirect responses<\/li>\n\n\n\n
  • Anything: Returns anything that is passed to request<\/li>\n<\/ul>\n\n\n\n
    When you click on a feature, it will display a list of accessible URLs. You can even try it out directly from within the browser.<\/p>\n\n\n\n
    For example, the most basic one (GET):<\/p>\n\n\n\n
    \"\"<\/p>\n\n\n\n
    It as no parameter and it will return headers sent by the browser or curl command.<\/p>\n\n\n\n
    This is a bit simple to use JMeter for, so let’s try another feature.<\/p>\n\n\n\n
    GET Links<\/h2>\n\n\n\n
    The other feature from httpbin I wanted to try is links<\/em>:<\/p>\n\n\n\n
    \"\"<\/p>\n\n\n\n
    It will return is a page full of links from 0 to n-1. For example with n equal 20:<\/p>\n\n\n\n
    \"\"<\/p>\n\n\n\n
    JMeter<\/h2>\n\n\n\n
    Let’s create a new JMeter Test Plan with the items required to have something to start with:<\/p>\n\n\n\n
      \n
    • A thread group<\/li>\n\n\n\n
    • HTTP Request<\/li>\n\n\n\n
    • Recording Controller<\/li>\n\n\n\n
    • Results Tree<\/li>\n<\/ul>\n\n\n\n
      \"\"<\/p>\n\n\n\n
      You can see that the path is hard coded, which means that you will need to change it if you want to test with additional links. I can add a User Parameters<\/em> preprocessor and declare a variable named number_of_links<\/code>. Path will then be changed to links\/${number_of_links}\/${number_of_links}<\/code>.<\/p>\n\n\n\n
      Under this initial HTTP request, I will add Regular Expression Extractor<\/em> to find all links from the resulting page. It will be set like this:<\/p>\n\n\n\n
      \"\"<\/p>\n\n\n\n
      All matches (match No. = -1) will be stored in links<\/code> variable. It will match what is between href='<\/code> and '><\/code>.<\/p>\n\n\n\n
      Next step is too loop on the list of links that were found, so let’s add a ForEach <\/em>controller:<\/p>\n\n\n\n
      \"\"<\/p>\n\n\n\n
      Input variable will be the one generated by Regular Expression Extractor<\/em> and output will be used in further HTTP requests within the loop.<\/p>\n\n\n\n
      Talking about HTTP request, here is how it will look like:<\/p>\n\n\n\n
      \"\"<\/p>\n\n\n\n
      In this one, I am using link<\/code> variable in Path parameter as well as the name. This will help to recognize request more easily in the Results Tree<\/em>.<\/p>\n\n\n\n
      Before running the test plan, here is the tree view of the full plan:<\/p>\n\n\n\n
      l\"\"<\/p>\n\n\n\n
      Once I start the test plan, Results tree<\/em> will be populated:<\/p>\n\n\n\n
      \"\"<\/p>\n\n\n\n
      Conclusion<\/h2>\n\n\n\n
      JMeter is not only a load test tool. With its programming capabilities (ie. logic controller), it can do much more.<\/p>\n\n\n\n
      And you, what are you doing with JMeter?<\/p>\n","protected":false},"excerpt":{"rendered":"
