Explain validation errors in more depth --------------------------------------- Key: ARQ-1567 URL: https://issues.jboss.org/browse/ARQ-1567 Project: Arquillian Issue Type: Enhancement Security Level: Public(Everyone can see) Components: Extension - Droidium Affects Versions: droidium_1.0.0.Alpha2 Reporter: Stefan Miklosovic In many cases, it is not sufficient to provide a user just with stack trace when something goes wrong, for example, from this one: {code} java.lang.IllegalStateException: Directory to check against readability is null object or empty string. at org.arquillian.droidium.container.configuration.Validate.notNullOrEmpty(Validate.java:98) at org.arquillian.droidium.container.configuration.Validate.isReadableDirectory(Validate.java:147) at org.arquillian.droidium.container.configuration.AndroidSDK.<init>(AndroidSDK.java:189) at org.arquillian.droidium.container.AndroidDeployableContainer.setup(AndroidDeployableContainer.java:153) {code} It basically says that user does not have specified JAVA_HOME but he can not know that without looking into sources which is *totally* not desired. Review all crucial configuration properties and its setters / getters and be sure that when it fails user knows whats going on.
