We proposed (1) a new automated technique for Java Script regression testing, which is based on inferring invariant assertions, (2) the first Java Script mutation testing tool, capable of guiding the mutation generation towards behaviour-affecting mutants in error-prone portions of the code, (3) an automatic technique to generate test cases for Java Script functions and events; Mutation analysis is used to generate test oracles, capable of detecting regression Java Script and DOM-level faults, and (4) utilizing existing DOM-dependent assertions as well as useful execution information inferred from a DOM-based test suite to automatically generate assertions for unit-level testing of Java Script functions.

To measure the effectiveness of the proposed approaches, we evaluated each method presented in this thesis by conducting various empirical studies and comparisons with existing testing techniques.

However, Java Script is loosely typed, dynamic, and notoriously challenging to analyze and test.

The work presented in this dissertation has focused on advancing the state-of-the-art in testing Java Script-based web applications by proposing a new set of techniques and tools.

A forward slice with respect to a statementst, indicates how an operand at st is being subsequently.

For thispurpose we apply a dynamic forward slice on the statements collected from a back-ward slice of a DOM-based assertion.
