Abstract

Embodiments of the present invention disclose a method, computer program product, and system for comparing screenshots of an application interface. In one embodiment, the method includes receiving test scenario parameters, wherein the parameters include a first screenshot of an application interface, one or more page objects associated with the first screenshot, generating a second screenshot of an updated application interface, identifying one or more page objects within the second screenshot based on a scope of each of the page objects associated with the first screenshot, comparing a section of the second screenshot to a section of the first screenshot that includes one or more page objects associated with the first screenshot that correspond to one or more page objects included in the section of the second screenshot, and determining whether the section of the second screenshot matches, within a predetermined tolerance level, the section of the first screenshot.

Claims13

Dependent claims

A computer program product for comparing screenshots of an application interface, the computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to set initial conditions that include a specified Web browser, a specific webpage, execution of program code, and input information;
program instructions to identify a document object model based on the set initial conditions;
program instructions to define a scope based on the identified document object model, wherein the scope defines outer boundaries of a section of the specific webpage associated with one or more page objects;
program instructions to identify the one or more page objects within the defined scope;
program instructions to create a first screenshot based on the defined scope;
program instructions to store the first screenshot and the identified one or more page objects;
program instructions to update the set initial conditions, wherein the updated initial conditions include at least an update to the specified webpage;
program instructions to receive parameters of a test scenario, wherein the parameters include the first screenshot and the identified one or more page objects;
program instructions to generate a second screenshot based on the first screenshot for the updated initial conditions;
program instructions to identify one or more page objects within the second screenshot based on a scope of each of the identified one or more page objects associated with the first screenshot in the parameters of the test scenario;
program instructions to compare a section of the second screenshot that includes the identified one or more page objects of the second screenshot to a section of the first screenshot that includes the identified one or more page objects associated with the first screenshot that correspond to the identified one or more page objects included in the section of the second screenshot, wherein the section is a partial screenshot that represents a portion of a full screenshot;
program instructions to determine whether the section of the second screenshot matches, within a predetermined tolerance level, the section of the first screenshot;
and
program instructions to provide a report based on the determination.

12 more elements

A computer system for comparing screenshots of an application interface, the computer system comprising:

one or more computer processors;
one or more computer readable storage media;
program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to set initial conditions that include a specified Web browser, a specific webpage, execution of program code, and input information;
program instructions to identify a document object model based on the set initial conditions;
program instructions to define a scope based on the identified document object model, wherein the scope defines outer boundaries of a section of the specific webpage associated with one or more page objects;
program instructions to identify the one or more page objects within the defined scope;
program instructions to create a first screenshot based on the defined scope;
program instructions to store the first screenshot and the identified one or more page objects;
program instructions to update the set initial conditions, wherein the updated initial conditions include at least an update to the specified webpage;
program instructions to receive parameters of a test scenario, wherein the parameters include the first screenshot and the identified one or more page objects;
program instructions to generate a second screenshot based on the first screenshot for the updated initial conditions;
program instructions to identify one or more page objects within the second screenshot based on a scope of each of the identified one or more page objects associated with the first screenshot in the parameters of the test scenario;
program instructions to compare a section of the second screenshot that includes the identified one or more page objects of the second screenshot to a section of the first screenshot that includes the identified one or more page objects associated with the first screenshot that correspond to the identified one or more page objects included in the section of the second screenshot, wherein the section is a partial screenshot that represents a portion of a full screenshot;
program instructions to determine whether the section of the second screenshot matches, within a predetermined tolerance level, the section of the first screenshot;
and
program instructions to provide a report based on the determination.
