Breaking spy_ema.csv EMA14 data doesn't break tests ComparesAgainstExternalData and ComparesAgainstExternalDataAfterReset

[femtotrader]

Expected Behavior

When changing data in EMA14 column with fake (wrong) values, tests should fail but they are still passing correctly.

Actual Behavior

The 2 tests in ExponentialMovingAverageTests

• ComparesAgainstExternalData
• ComparesAgainstExternalDataAfterReset

are passing successfully... even if data in EMA14 column are wrong

Potential Solution

should be discussed
