I've been testing my ink! contract and one of the tests failed.
The test that failed:

#[ink::test]
fn get_bids_made_works() {
    let bid = 100u128;
    let mut bag = Moneybag::new(bid);
    let accounts = default_accounts::<DefaultEnvironment>();
    let bob: AccountId = accounts.bob;
    set_caller::<DefaultEnvironment>(bob);
    bag.add_bid(bid).unwrap();
    assert_eq!(bag.get_bids_made(), 3);       
}  

The Error message:

 Finished test [unoptimized + debuginfo] target(s) in 2.76s
     Running unittests src/lib.rs (target/debug/deps/moneybag-1ffd8ca9ab27f17f)
error: test failed, to rerun pass '--lib'
ERROR: `"/home/creestl/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/cargo" "test" ""` failed with exit code: Some(101)

From the error message it is not clear which test function that was. But to me it was just obvious that it was the get_bids_made_works that I've provided above. But what if it was not so obvious? And what if instead of 6 tests I had 50?
I see that in the error message there is a "test" "" part. And I suppose that it should include the name of the test function, but it does not. Should I use some macro to define test's name? e.g.:

#[ink::test]
#[ink::test_name("NiceTest")]
. 
.
.

How do I distinguish one failed test from another?

  • Can you try using cargo +nightly test instead of cargo +nightly contract test and post the output here? The latter doesn't provide very helpful output (see github.com/paritytech/cargo-contract/issues/421).

  • Oh wow, it really gives a much more detailed output. I was using cargo +nightly contract test just because of this line. But your advise solved the problem.

Use cargo +nightly test instead of cargo +nightly contract test
