+# Add player
+
+This chapter shows how to add a text to a game.
+
+## First test: an `App` has no text
+
+```rust
+fn test_empty_app_has_text() {
+    let mut app = App::new();
+    assert_eq!(count_n_texts(&mut app), 0);
+}
+```
+
+## Second test: can create an `App` with text
+
+```rust
+fn test_can_create_app_from_str() {
+    create_app(String::from("irrelevant"));
+}
+```
+
+## Third test: an `App` has text
+
+```rust
+fn test_app_has_text() {
+    let mut app = create_app(String::from("irrelevant"));
+    app.update();
+    assert_eq!(count_n_texts(&mut app), 1);
+}
+```
+
+## Fourth test: an `App` has the correct text
+
+```rust
+fn test_app_uses_text() {
+    let text = String::from("some random text");
+    let mut app = create_app(text.clone());
+    app.update();
+    assert_eq!(get_text(&mut app), text);
+}
+```
+
+## Conclusion
+
+We can now create an `App` with a text.
+We have tested everything that the App does!
