Rule	Effect
AssertDatabaseTableToModelClassRector	Replaces a database-assertion table string with the matching Eloquent model class
AssertModelExistsRector	Replaces an assertDatabaseHas/Missing single-id check with assertModelExists/Missing

AssertDatabaseTableToModelClassRector

-$this->assertDatabaseHas('users', ['email' => $email]);
+$this->assertDatabaseHas(\App\Models\User::class, ['email' => $email]);

A model class is rename-safe and navigable, where a table string rots silently when the table is renamed. Laravel resolves the table from the model, so behaviour is unchanged.

The rule inserts the fully-qualified name. Add ->withImportNames() to your Rector config and it lands as a short User::class with the use statement added for you.

• Applies to assertDatabaseHas, assertDatabaseMissing and assertDatabaseCount, called as $this->…, self::… or static::… inside a PHPUnit TestCase subclass. assertSoftDeleted and assertNotSoftDeleted are excluded: with a model they also resolve the deleted-at column, so a table match alone does not prove behaviour is preserved.
• The string is rewritten only when the resolved model's own table provably equals it. A model with a mismatched $table, an overridden getTable(), or no resolvable model at all is left untouched, so expect the occasional string the rule declines to convert.
• Configurable via model_namespace (default App\Models) and a table_to_model map for tables the singularise-and-studly convention cannot resolve. A map entry is still verified, never trusted blindly.

AssertModelExistsRector

-$this->assertDatabaseHas(Article::class, ['id' => $article->id]);
-$this->assertDatabaseMissing(Article::class, ['id' => $article->id]);
+$this->assertModelExists($article);
+$this->assertModelMissing($article);

• Fires when argument 1 is SomeModel::class, argument 2 is a single-item ['id' => $var->id] array, and PHPStan can confirm $var is typed as SomeModel.
• Accepts a class-constant key (SomeModel::ID) when the constant resolves to 'id'.
• Skips three-argument calls: the third is a connection name, and dropping it would silently switch connections.
• Skips multi-key arrays, which assert attribute values rather than existence.
• Fires only inside a PHPUnit\Framework\TestCase subclass, on $this or self::/static::, so a non-test helper with a same-named method is left alone.
