FORM _SUBMIT_BUTTON SubmitButtont prNJS2 return false type submit gt Unlike the XPath or Regular expression variables which can tolerate content changes to some extent JavaScript variables are vulnerable to content changes due to the search logic Because the index is used to identify the value of the source content in case the application returns more or less script blocks in the page content compared to that of recorded the value won t be found and the playback fails Therefore when an application under test AUT is a web application that returns dynamic content JavaScript variables that were auto generated during recording may need to be manually removed or replaced by Regular Expression variables in order to have the script successfully playback Tip 5 Notice that script editing can be done better in Tree view rather than Java Code view in most cases OpenScript provides users a choice of viewing script content in two different interfaces Tree View and Java Code view Tree view shows navigation nodes in graphical user interface and Java Code view shows the command in pure Java syntax Users can select which interface they use to view develop and edit scripts depending on their technical preference Two views can be easily flipped back and forth by clicking the tabs When Java Code tab is clicked Java Code view shows the corresponding lines of code that were selected in the Tree view The below figures show the screenshots

104. urned a page that is totally different than that of recorded thus the matching string does not exist in the playback content The reason why the unexpected page was returned could be a server side error or an invalid request sent by the script Case A is typically seen when page content is dynamic often when a databank that parameterizes the user entry is added to the script For example a script was recorded against a shopping website using the user account Tom The web site returns a page based on Tom s purchase history But if a different user account Jennifer is used to sign in at the script playback the website returns a page based on Jennifer s preferences which is different from Tom s From the application s perspective this is a legitimate difference however from the script perspective this is nothing but a different page returned from the application Load testing scripts in OpenScript employs a concept of correlation which is a method to identify a parameter that changes in different sessions and to substitute that parameter with a valid value dynamically during playback The correlation expects to find a matching string from the page content using search strings defined in the correlation variables The search strings vary from the types of variables and can be Regular expressions XPath expressions or JavaScript index The variables can find the value as long as their string extraction logic is valid against the
105. use wrong page content was returned by the server or a correct page was returned but a variable set in that page could not extract the target value from the page content As a high level guideline when the Content Similarity rate of a failed navigation is more than 90 there is a good chance that it is a valid page and variable definition simply needs more reinforcement On the other hand if the similarity rate is lower than 90 it could be that an invalid page is returned by the application and further verification is recommended Note when a percentage is significantly smaller the variable that appears in the error message may be unrelated to the root cause of the failure 6 Similarity rate shows the similarity of the page in percentage So the higher the the more similar the pages are between record and playback But when small page content or binary content is compared a small percentage may be shown even for a valid page For example when comparing a page with a single line content Welcome Tom if during playback the page has Welcome Jennifer then the content similarity will be 50 7 This point is discussed in Tip 2 in this paper 10 25 TIPS FOR CREATING EFFECTIVE LOAD TEST SCRIPTS USING ORACLE LOAD TESTING FOR E BUSINESS SUITE AND FUSION APPLICATIONS In this scenario the script playback failed with the Failed to solve variable error however the similarly rate of the failed navigation is 99 Troubleshooting step
