Is there an infinite capacity and zero capacity bucket available for testing?

[etnoy]

I am learning bucket4j and am trying to figure out a good way to simulate different scenarios in my testing. In these tests I want to simulate both a bucket that always allows consumption, and another bucket that never allows. With this, I can test my code that handles both scenarios.

My first approach is to simply mock the bucket4j which does work, but it doesn't feel that elegant.

Instead, I created a bucket interface which can be implemented by test buckets. However, I can't really create a zero capacity bucket. I can create a bucket with availability one and then instantly consume the last capacity, but it isn't that great. For the inifinite bucket, I created a bucket that adds one every nanosecond.

Is it possible to create an ideal infinite and zero bucket? LIke

// Zero capacity
bucketBuilder.addLimit(Bandwidth.simple(0));

// Infinite capacity
bucketBuilder.noLimit()

Hello @etnoy

It is not possible to achive via builder but, can be simulated in the following way:

Effectively empty:

Bucket bucket = ...;
bucket.consumeIgnoringRateLimits(Long.MAX_VALUE / 2);
System.out.println(bucket.getAvailableTokens());

Effectively infinite:

Bucket bucket = ...;
bucket.forceAddTokens(Long.MAX_VALUE / 2);
System.out.println(bucket.getAvailableTokens());
