jest/no-large-snapshots Style ​

What it does ​

When using Jest's snapshot capability one should be mindful of the size of created snapshots. As a general best practice snapshots should be limited in size in order to be more manageable and reviewable. A stored snapshot is only as good as its review and as such keeping it short, sweet, and readable is important to allow for thorough reviews.

Example ​

javascript
// invalid
exports[`a large snapshot 1`] = `
line 1
line 2
line 3
line 4
line 5
line 6
line 7
line 8
line 9
