What do I need to test it by myself

Since the server is written in Java, you need at least a JRE for the server. First download the server bundle from the files section. After extracting it, you can immediately start the server by executing the startServer.bat (Windows) or startServer.sh (Mac/Linux) file. Now you probably want to access the server from your application. For that you just need two jars in your classpath, the sqlspaces-commons and sqlspaces-client jar. Then go ahead and execute the test class that you can find under quickstart. If you have any problems, check if the documentation here can help you and otherwise feel free to contact us!
