### Description

I use coverlet to analyze code coverage and as you can see it from this build: [AppVeyor](https://ci.appveyor.com/project/Giorgi/entityframework-exceptions/builds/32130967) it reports about 72% code coverage. On the other hand [Codecov](https://codecov.io/gh/Giorgi/EntityFramework.Exceptions) reports 62%. The same report is uploaded to coveralls as well and it is reported correctly: [Giorgi/EntityFramework.Exceptions | Coveralls - Test Coverage History & Statistics](https://coveralls.io/github/Giorgi/EntityFramework.Exceptions)

### Repository

> **[GitHub - Giorgi/EntityFramework.Exceptions: Strongly typed exceptions for Entity Framework...](https://github.com/Giorgi/EntityFramework.Exceptions)**
>
> Strongly typed exceptions for Entity Framework Core. Supports SQLServer, PostgreSQL, SQLite, Oracle and MySql.

Hi @Giorgi, thanks for writing in. This actually has to do with how we calculate coverage. You can read about it here: [Frequently Asked Questions](https://docs.codecov.io/docs/frequently-asked-questions#section--how-is-coverage-calculated-)

Short story is that we do not consider partially covered lines to be covered.

If you take a look at the Appveyor build at the bottom  
[https://ci.appveyor.com/project/Giorgi/entityframework-exceptions/builds/32130967](https://ci.appveyor.com/project/Giorgi/entityframework-exceptions/builds/32130967)

and the Codecov build  
[https://codecov.io/gh/Giorgi/EntityFramework.Exceptions/tree/151e1633930de300963497b5143978f5ddc1b08a](https://codecov.io/gh/Giorgi/EntityFramework.Exceptions/tree/151e1633930de300963497b5143978f5ddc1b08a)

You’ll see that the Appveyor (and presumably Coveralls) considers partials lines to be covered.

For example, for `EntityFramework.Exceptions.Sqlite`, you see that we are showing 69.23% for 9 lines covered over 13. If you include the partial line (10/13 = 76.92%), you see it match with what is showing in CI. The same came be done for each file.
