Track missing type coverage to ensure type safety

typecov's Issues

`New untyped symbols: 0` should never fail

Change: +100.00% Total: 100.00% (min. 100.00%) New untyped symbols: 0

Allow specify other options like ignoreFiles, ignoreCatch or atLeast

type-coverage package supports some options which might be useful (like ignoreFiles or ignoreCatch).

Also its CLI has option --at-least and I believe type-coverage-watcher might have that option also and fail if a coverage is down.

Comparison should use rounded values

Currently the comparison used for success/failure compares the unrounded values before they are formatted for display:

https://github.com/codechecks/typecov/blob/master/src/index.ts#L47

As a result, situations are possible where the rendered percentages are the same but the check fails.

Example:

### Current type coverage: 95.00%

Minimum acceptable type coverage: 95.00% — 🔴

atLeast: 95
headTypeCoverage: 94.999

Another example:

### Current type coverage: 40.63%
Minimum acceptable type coverage: 40.63% — 🔴

correctCount: 26
totalCount: 64
headTypeCoverage: 40.625

Typecov warns on try/catch error

Hey,

Typecov warns on the catch(e)

try {
 throw new Error()
} catch(e) {
  console.log(e);
}

But Typescript warns with this Catch clause variable cannot have a type annotation

Typecov should ignore catch
