nestjs test fails

Comment

Nestjs testing module not found

{
  ...
  "moduleNameMapper": {
    "^@Shared/(.)*$": "<rootDir>/src/app/shared/$1"
  }
}

If you're coming from google then this can also happen if VSCode autocompletes your imports as src/xyz/abc/service.ts instead of ../xyz/abc/service.ts.

When running tests the test code won't be able to locate the correct service(s) at run-time. It needs fully relative paths without an absolute 'src/' at the beginning.

As you are using typescript's path mapping, you need to also update your jest config with the mapped paths as well. Your jest config needs to have the following added:Assuming that your is set to be . and not ./src. You can find more info on it here. https://kulshekhar.github.io/ts-jest/user/config/#paths-mapping

# This function doubles the input value
def double(x):
  return 2*x
 
# Apply this function to double every value in a specified column
df.column1 = df.column1.apply(double)
 
# Lambda functions can also be supplied to `apply()`
df.column2 = df.column2.apply(lambda x : 3*x)
 
# Applying to a row requires it to be called on the entire DataFrame
df['newColumn'] = df.apply(lambda row: 
  row['column1'] * 1.5 + row['column2'],
  axis=1
