How to detect whether android app is running UI test with Espresso
Building on the answers above the following Kotlin code is equivalent:
val isRunningTest : Boolean by lazy {
try {
Class.forName("android.support.test.espresso.Espresso")
true
} catch (e: ClassNotFoundException) {
false
}
}
You can then check the value of the property:
if (isRunningTest) {
// Espresso only code
}
Combined with CommonsWare's comment. Here is my solution:
I defined an AtomicBoolean
variable and a function to check whether it's running test:
private AtomicBoolean isRunningTest;
public synchronized boolean isRunningTest () {
if (null == isRunningTest) {
boolean istest;
try {
Class.forName ("myApp.package.name.test.class.name");
istest = true;
} catch (ClassNotFoundException e) {
istest = false;
}
isRunningTest = new AtomicBoolean (istest);
}
return isRunningTest.get ();
}
This avoids doing the try-catch check every time you need to check the value and it only runs the check the first time you call this function.
Combining Commonsware comment + Comtaler's solution here's a way to do it for any test class using the Espresso framework.
private static AtomicBoolean isRunningTest;
public static synchronized boolean isRunningTest () {
if (null == isRunningTest) {
boolean istest;
try {
Class.forName ("android.support.test.espresso.Espresso");
istest = true;
} catch (ClassNotFoundException e) {
istest = false;
}
isRunningTest = new AtomicBoolean (istest);
}
return isRunningTest.get();
}
