If so, these checks should be inverted, in AssertJ `assertThat(...)` should always contain the actual value, not the expected. Reagrdless of this, the size comparison can be simplified like: ```java assertThat(deserialized.getLastEndTimestamp()).isEqualTo(state.getLastEndTimestamp()); assertThat(deserialized.getUnassigned()).hasSameSizeAs(state.getUnassigned()); assertThat(deserialized.getPending()).hasSameSizeAs(state.getPending()); ``` -- This is an automated message from the Apache Git Service.
