Sandbox
Create and manage temporary folders to simplify integration testing
Usage
Add sandbox as a dependency (you probably only want it for tests). Maven dependency info:
<dependency>
<groupId>net.avh4.util</groupId>
<artifactId>sandbox</artifactId>
<version>0.0.6</version>
<scope>test</scope>
</dependency>
Any code that wants to play in the sandbox should have a root path that can be injected:
public class MyService {
private final File root;
public MyService(File root) {
this.root = root;
}
public void doSomething() {
File configFile = new File(root, "config.xml");
File fileToWrite = new File(root, "output.txt");
...
}
}
Create a sandbox and populate it with some files. This example copies test-config.xml from the classpath into config.xml in the sandbox.
Sandbox sandbox = new Sandbox();
sandbox.useResource("test-config.xml", "config.xml");
Test your code in the sandbox.
MyService service = new MyService(sandbox.getRoot());
assert(sandbox.newFile("output.txt").exists() == true);
