Same error... What could be wrong?

[jeanPokou]

I am facing the same issue too

[hitherejoe]

The following will fix this:

@Test
fun isProjectsCacheExpiredReturnsNotExpired() {
    cache.setLastCacheTime(System.currentTimeMillis() - 1000).test()
    val testObserver = cache.isProjectsCacheExpired().test()
    testObserver.assertValue(false)
}

Sorry about that, I was using the incorrect value for the cache check. Here we now:

• Save the current time (minus 1000) as the last cache time
• Check whether the cache has expired using currentTime - it.lastCacheTime > expirationTime

Here, previously lastCacheTime was 1000 which meant the incorrect value was always being used in the calculation. @jeanPokou @AlanUeyn @ninad458 does this work for you here?

[jeanPokou]

Thanks, @hitherejoe It is working now

Hello Joe.

It remains with error for the test of test method isProjectsCacheExpiredReturnsNotExpired:

Also the same error happens for this other test method isProjectsCacheExpiredReturnsExpired.

Hi, @graffiti75 what version of Robolectric are you using? you should upgrade to 4.0.2. I was finally able to make it work with

    @Test
    fun isProjectCacheReturnsExpired() {
        projectsCacheLocal.setLastCacheTime(1000L).test()
        projectsCacheLocal.isProjectsCacheExpired().test().assertValue(true)
    }
   @Test
    fun isProjectsCacheReturnsNotExpired() {
        projectsCacheLocal.setLastCacheTime(System.currentTimeMillis()).test()
        projectsCacheLocal.isProjectsCacheExpired().test().assertValue(true)
    }

Here is the isProjectsCachedExpired function

   override fun isProjectsCacheExpired(): Single<Boolean> {
        val currentTime = System.currentTimeMillis()
        val expirationInterval =(1000 * 60 * 60 ).toLong() // 1 hour
        return  projectsDataBase.configDao().getConfig()
            .single(
            // if config empty set last cache time to zero
            Config(lastCacheTime = 0)).map {
            currentTime - it.lastCacheTime > expirationInterval
        }
    }

Ps: You may have differents functions names

Robolectric

Version 3.4.2.

I tried updating the Robolectric version, but the same errors persists.
