I was not able to cover all the lines even though I did tests that went over those lines. |

You have to change much more code in themodules
and use good mocks in the tests
| class Line { | ||
| constructor({ point1 = new Point(), point2 = new Point(), n = undefined, slope = undefined }) { | ||
| constructor({ point1 = new Point(), point2 = new Point(), n = undefined, slope = undefined }) { | ||
| this.point1 = point1; |

you have to add more checks in the function
what happens when point is an array, what happens when n is a string etc...

jest cannot be in the dependency section

why didn't you change the code?

here you don't call this function, you test a different function

missing the errors
and the coverage for this module is under 70

Don't call functions inside the tests beside the function that you test
You have to see that other functions will be getting called inside the tested function
use mocks for a function that is being called inside an other one

I want to move on to the next task. |

| this.point2 = point2; | ||

if n is not undefined but is also not a number
if slope is not undefined but also not a number???
| throw new Error('the type of point is not Point') | ||

| proxyLine.calculateSlope() | ||
| if (line.slope === proxyLine.slope) { |

Who said that the line's slope is already calculated?

I installed it when I didn't manage with the tests, but in the end I managed.

Did you change code? |

Continue working on this task

Throw directly an error, like this, you don't mix up checks and codes

remove the remarks and console before pushing the commit

don't execute a different function in a unittest

Where are the mocks in the tests?
