Acceptance testing of web applications with Test Description Language

Olek Ł., Alchimowicz B., Nawrocki J.

Computer Science

2014

Vol. 15 (4)

459--477

Acceptance tests are usually created by a client after a part of a system is implemented. However, some methodologies propose the elaboration of test cases before implementing a system. This approach increases the probability of system implementation that fulfills requirements, but may be problematic for customers and testers. To allow acceptance testing in such conditions, we propose to define test cases by recording them on an interactive mockup (a low detailed user-interface prototype). The paper focuses on Test Description Language, a notation used to store test cases.

Generating Syntax Diagrams From Regular Expressions

Alchimowicz B., Nawrocki J.

Foundations of Computing and Decision Sciences

2011

Vol. 36, No. 2

In some web applications there are fields and each field has its syntax. Usually that syntax is described with regular expressions. Programmers use them to instruct computer which input is correct and which is not. If the input is incorrect a user would like to know why it is wrong. One solution could be just to present the regular expression. Unfortunately many users are IT-laymen and they can not read regular expressions. Another solution would be to write a section in a user manual explaining which input is syntactically correct and which is not. Regrettably, that is a time consuming process. Thus, a question arises, if such a description could be generated automatically. The paper presents an experimental system that automatically generates an explanation of a given regular expression. This paper focuses on problem of generating syntax diagrams from regular expressions.
