Abstract

A method for generating test steps for a web application includes making a first determination that a test case for the web application has failed. The method further includes receiving a most recent historical document object model (DOM) state, and receiving a first current DOM state from a DOM storage. Further, the method includes comparing the most recent historical DOM state and the first current DOM state to receive a set of DOM differences. In addition, the method includes determining, using an identification engine, a set of elements and patterns based on the set of DOM differences. Further, the method includes generating, using a test step engine, modified test steps for the test case to receive a modified test case. The method also includes receiving an approval of the modified test case and executing, in response to the approval, the modified test case using the modified test steps.

Claims17

Dependent claims

A method for generating test steps for a web application, the method comprising:

making a first determination that a test case for the web application has failed;
receiving, in response to the first determination, a most recent historical document object model (DOM) state and a first current DOM state from a DOM storage, wherein the most recent historical DOM state and the first current DOM state are associated with the web application;
comparing, using a comparison engine, the most recent historical DOM state and the first current DOM state to receive a set of DOM differences;
determining, using an identification engine, a set of elements and patterns based on the set of DOM differences;
generating, using a test step engine, modified test steps for the test case based on the set of elements and patterns to receive a modified test case;
receiving an approval of the modified test case;
executing, in response to the approval, the modified test case using the modified test steps;
receiving, based on the execution of the modified test case, a second current DOM state, wherein the second current DOM state is associated with the web application;
making a second determination that execution of the modified test case generated an error;
comparing, based on the second determination, the first current DOM state and the second current DOM state to receive a second set of DOM differences;
generating second modified test steps for the modified test case based on the second set of DOM differences to obtain a second modified test case;
and
executing the second modified test case.

A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for generating test steps for a web application, the method comprising:

receiving a most recent historical document object model (DOM) state and a current DOM state from a DOM storage, wherein the most recent historical DOM state and the current DOM state are associated with the web application;
comparing the most recent historical DOM state and the current DOM state to receive a set of DOM differences;
generating modified test steps for a test case based on the set of DOM differences to receive a modified test case, wherein the test case tests one or more features of the web application;
executing the modified test case using the modified test steps;
receiving, based on the execution of the modified test case, a second current DOM state, wherein the second current DOM state is associated with the web application;
making a second determination that execution of the modified test case generated an error;
comparing, based on the second determination, the current DOM state and the second current DOM state to receive a second set of DOM differences;
generating second modified test steps for the modified test case based on the second set of DOM differences to obtain a second modified test case;
and
executing the second modified test case.
