+# Disallow conditional logic in tests (`no-conditional-in-test`)
+
+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 a conditional statement will usually be better served by a test
+devoted to it.
+
+## Rule Details
+
+This rule reports on any use of a conditional statement such as `if`, `switch`,
+and ternary expressions.
+
+Examples of **incorrect** code for this rule:
+
+```js
+it('foo', () => {
+  if (true) {
+    doTheThing();
+  }
+});
+
+it('bar', () => {
+  switch (mode) {
+    case 'none':
+      generateNone();
+    case 'single':
+      generateOne();
+    case 'multiple':
+      generateMany();
+  }
+
+  expect(fixtures.length).toBeGreaterThan(-1);
+});
+
+it('baz', async () => {
+  const promiseValue = () => {
+    return something instanceof Promise
+      ? something
+      : Promise.resolve(something);
+  };
+
+  await expect(promiseValue()).resolves.toBe(1);
+});
+```
+
+Examples of **correct** code for this rule:
+
+```js
+describe('my tests', () => {
+  if (true) {
+    it('foo', () => {
+      doTheThing();
+    });
+  }
+});
+
+beforeEach(() => {
+  switch (mode) {
+    case 'none':
+      generateNone();
+    case 'single':
+      generateOne();
+    case 'multiple':
+      generateMany();
+  }
+});
+
+it('bar', () => {
+  expect(fixtures.length).toBeGreaterThan(-1);
+});
+
+const promiseValue = something => {
+  return something instanceof Promise ? something : Promise.resolve(something);
+};
+
+it('baz', async () => {
+  await expect(promiseValue()).resolves.toBe(1);
+});
