### Question:
Eth1VotingPeriod { public UInt64 getCacheDurationInSeconds() { return cacheDuration; } Eth1VotingPeriod(); UInt64 getSpecRangeLowerBound(final UInt64 slot, final UInt64 genesisTime); UInt64 getSpecRangeUpperBound(final UInt64 slot, final UInt64 genesisTime); UInt64 getCacheDurationInSeconds();  }### Answer:
@Test void shouldCalculateCacheDuration() { assertThat(votingPeriod.getCacheDurationInSeconds()).isEqualTo(UInt64.valueOf(67)); }
