+### `Testing.prototype.toEqual()`
+
+Executes the spec on a state `true` from the `execute` expecting the provided `value` to equal to the given `expected`.
+
+> "Expect the actual `value` to be equal to the `expected`, using deep equality comparison."
+
+```typescript
+public toEqual(
+  expectation: string,
+  value: any,
+  expected: any,
+  execute?: boolean
+): this {
+  this.it(expectation, () => expect(value).toEqual(expected), execute);
+  return this;
+}
+```
+
+**Parameters:**
+
+| Name: type            | Description |
+| :-------------------- | :---------- |
+| `expectation: string` | "Textual description of what this spec is checking" with an optional its unique number when adding `[counter]` |
+| `value: Value`        | The value of any type passed to the [`expect()`][jasmine-expect] function of jasmine |
+| `expected: boolean`   | The value of any type passed to the `toEqual()` method of jasmine. "The expected value to compare against." |
+| `execute: boolean`    | Whether or not to execute the spec, by default it's set to `true` |
+
+**Returns:**
+
+The **return value** is an instance of a [`Testing`](#testing).
+
+**Usage:**
+
+```typescript
+// Example usage.
+// Class.
+import { Testing } from '@angular-package/testing';
+/**
+ * Initialize testing.
+ */
+const testing = new Testing(true, true);
+/**
+ * toEqual()
+ */
