Code review comment: ```suggestion         // Only tests in packages are executed so that the default packages (i.e. single BAL files), which have the package name ```

Code under review:
public void execute(BuildContext buildContext) {
        Path sourceRootPath = buildContext.get(BuildContextField.SOURCE_ROOT);

        Map<BLangPackage, TestarinaClassLoader> programFileMap = new HashMap<>();
        List<BLangPackage> moduleBirMap = buildContext.getModules();
        
        
        
        for (BLangPackage bLangPackage : moduleBirMap) {
            PackageID packageID = bLangPackage.packageID;

            if (!buildContext.moduleDependencyPathMap.containsKey(packageID)) {
                continue;
            }

            if (Files.notExists(jarPath)) {
                jarPath = modulejarPath;
            }

            HashSet<Path> moduleDependencies = buildContext.moduleDependencyPathMap.get(packageID).platformLibs;
            
            HashSet<Path> dependencyJarPaths = new HashSet<>(moduleDependencies);
