failing tests in Pharo 7
Locked
 
|
It great having a CI system to check all our tests a passing,
but I thought I'd go old school and run them from the TestRunner GUI and found in a fresh latest Pharo 7 there are "128 failures, 63 errors" This one is interesting... ArrayTest>>test0FixtureAsSetForIdentityMultiplinessTest | anElement res | self elementsCopyNonIdenticalWithoutEqualElements. anElement := self elementsCopyNonIdenticalWithoutEqualElements anyOne. self deny: anElement copy == anElement. "<<<<FAILS" where anElement ==> SmallFloat64 (1.5) so the deny fails. It seems that the test setUp is wrong since #elementsCopyNonIdenticalWithoutEqualElements does not return a collection (of elements for which copy is not identical ) without equal elements:" This seems like a permanent error rather than a transient one. How does this slip through CI testing? and what can be done about cleaning this up? cheers -ben P.S. With the loss of method version info is impossible to guess when this may have been introduced, to guess which Issue it was related to, to guess how I might approach fixing this myself. |

So that was Pharo64bit. Pharo32bit is better with only has only "1 failures, 20 errors". So what is the CI dependency of the 32 bit and 64 bit Images? Do they both run tests independently? cheers -ben

I get about the same in 32-bit. I'm too worried about the release tests, although being totally clear would be really nice. Errors: On 7 January 2018 at 05:55, Sven Van Caekenberghe <[hidden email]> wrote:

(client := ZnClient new) get: 'http://gforge.inria.fr/frs/?group_id=1299'. and that url opens okay in Chrome web browser, so I don't know what to make of it. In Pharo-7.0.0-alpha.build.410.sha.aa40385.arch.32bit I also get a bunch of errors for SystemDependenciesTest that seem to have the same root cause...

I think we just got (un)lucky this time. #testRedirect connects to http://zn.stfx.eu, so it could well be an intermittent internet connection issue. What would we lose by restructuring the tests to use an internal server? My initial reaction is that an increase in test reliability would outweigh any loss of testing.

I know, but most (functional) tests *ARE* internal (are running against a server created just for the test). The remaining are there because HTTP *IS* a network communication protocol where it is important to test against servers 'out there in the wild'. It would be too limiting to exclude the networking (with its connectivity and timing issues) and the fact that there are hundreds of server and TLS/HTTPS implementations out there. Splitting the tests in two group might be a first step. > Cheers, > Alistair > > > > > >>> Cheers, >>> Alistair >>> >>> >>> >>>> It seems that the test setUp is wrong since >>>> #elementsCopyNonIdenticalWithoutEqualElements >>>> does not return a collection (of elements for which copy is not identical ) >>>> without equal elements:" >>>> >>>> This seems like a permanent error rather than a transient one. >>>> How does this slip through CI testing? >>>> and what can be done about cleaning this up? >>>> >>>> cheers -ben >>>> >>>> P.S.

In 64-bits SmallIntegers, Characters /and/ SmallFloat64s are all immediate so will always be #== to any instance of the same value. In 32-bits there are no instances of SmallFloat64. In 64-bits any float whose exponent falls within the single precision range (which excludes Inf & NaN) will be represented as a SmallFloat64. >>> >>> Which platform and image? >>> >>> Pharo 7.0 >>> Build information: >>> Pharo-7.0+alpha.build.410.sha.aa40385cd6fee69bb51d4a3afcacfb5f91eed206 >>> (32 Bit) >>> Ubuntu 16.04 >>> >>> 14915 run, 14859 passes, 31 skipped, 50 expected failures, 5 failures, >>> 1 errors, 0 unexpected passes >>> Failures: >>> ReleaseTest>>#testMethodsWithUnboundGlobals >>> TonelWriterTest>>#testWriteSnapshot >>> ReleaseTest>>#testUnpackagedClasses >>> ReleaseTest>>#testNoEmptyPackages >>> ReleaseTest>>#testThatAllMethodsArePackaged >>> >>> Errors: >>> ZnClientTests>>#testRedirect >> >> Hmm, strange.
