As the validation of BPEL processes against the official BPEL XML schema leaves room for a plethora of static errors, the specification contains 94 static analysis rules to cover all static errors. According to the specification, any violations of these rules are to be checked by a standard conformant engine at deployment time. When a violation is not detected in BPEL processes during deployment, such errors are only detectable at runtime, making them expensive to find and fix. Due to the large amount of rules, we have created a tag system to categorize them, allowing easier reasoning about these rules. Next, we formalized the static rules and derived test cases based on these formalizations with the aim to evaluate the degree of support for static analysis of BPEL engines. Hence, this work is the foundation of the static analysis capabilities of BPEL engines.engSOABPELstatic analysistestsformalization004workingpaperurn:nbn:de:bvb:473-opus4-464076
