android.util.Log class override for unit tests

README.md

This is an override of the android.util.Log class to allow testing code which calls Log methods.

Place these two classes in src/test/java/android/util.

To enable or disable logging to stdout just change the enablePrinting variable.

LogTestConfig.enablePrinting = true;

Log.java

package android.util;

public class Log {

    public static int v(String tag, String msg) {
        print("VERBOSE", tag, msg);
        return 0;
    }

    public static int d(String tag, String msg) {
        print("DEBUG", tag, msg);
        return 0;
    }

    public static int i(String tag, String msg) {
        print("INFO", tag, msg);
        return 0;
    }

    public static int w(String tag, String msg) {
        print("WARN", tag, msg);
        return 0;
    }

    public static int e(String tag, String msg) {
        print("ERROR", tag, msg);
        return 0;
    }

    private static void print(String type, String tag, String msg) {
        if (LogTestConfig.enablePrinting) {
            System.out.println(type + ": " + tag + ": " + msg);
        }
    }
}

LogTestConfig.java

package android.util;

public class LogTestConfig {
    public static boolean enablePrinting = false;
}
