Disallow conditional logic (no-if)
Conditional logic in tests is usually an indication that a test is attempting to cover too much, and not testing the logic it intends to. Each branch of code executing within an if statement will usually be better served by a test devoted to it.
Conditionals are often used to satisfy the typescript type checker. In these cases, using the non-null assertion operator (!) would be best.
Rule Details
This rule prevents the use of if/ else statements and conditional (ternary) operations in tests.
The following patterns are considered warnings:
it('foo', () => {
if ('bar') {
// an if statement here is invalid
// you are probably testing too much
}
});
it('foo', () => {
const bar = foo ? 'bar' : null;
});
These patterns would not be considered warnings:
it('foo', () => {
// only test the 'foo' case
});
it('bar', () => {
// test the 'bar' case separately
});
it('foo', () => {
function foo(bar) {
// nested functions are valid
return foo ? bar : null;
}
});
When Not To Use It
If you do not wish to prevent the use of if statements in tests, you can safely disable this rule.
