Shell/SSH zum Schlüsselbund hinzufügen.md

+It is not possible to add private key to Keychain, but you can store passphrase for private key in Keychain. On OSX, the native `ssh-add` command has a special argument to save the private key's passphrase in the OSX Keychain, which means that your normal login will unlock it for use with ssh. On OSX Sierra and later, you also need to configure SSH to always use the Keychain (see Step 2 below).
+
+Alternatively you can use a key without a passphrase, but if you prefer the security that's certainly acceptable with this workflow.
+
+## Step 1 - Store passphrase in the Keychain
+
+In the latest version of MacOS (12.0 Monterey), just do this once:
+
+```
+ssh-add --apple-use-keychain ~/.ssh/[your-private-key]
+```
+
+Or in versions of MacOS older than 12.0 Monterey, use:
+
+```
+ssh-add -K ~/.ssh/[your-private-key]
+```
+
+Enter your key passphrase, and you won't be asked for it again.
+
+(If this fails, make sure you are using Apple's version of `/usr/bin/ssh-add` and not something installed with brew etc.; check with `which ssh-add`)
+
+## Step 2 - Configure SSH-agent to always use the Keychain
+
+(Note: In versions of OSX prior to Sierra, this is not necessary)
+
+It seems that OSX Sierra removed the convenient behavior of persisting your keys between logins, and the update to ssh no longer uses the keychain by default. Because of this, you need to change one more thing for secure persistent key storage.
+
+The solution is outlined in [this github thread comment](https://github.com/lionheart/openradar-mirror/issues/15361#issuecomment-270242512). Here's what you do:
+
+1.  Ensure you've completed Step 1 above to store the passphrase in the keychain.
+    
+2.  If you haven't already, create an `~/.ssh/config` file. In other words, in the `.ssh`directory in your home dir, make a file called `config`.
+    
+3.  In that `.ssh/config` file, add the following lines:
+    
+    ```
+    Host *
+        UseKeychain yes
+        AddKeysToAgent yes
+        IdentityFile ~/.ssh/id_rsa
+    ```
+    
+    Change `~/.ssh/id_rsa` to the actual filename of your private key. If you have other private keys in your `~/.ssh` directory, also add an `IdentityFile` line for each of them. For example, I have one additional line that reads `IdentityFile ~/.ssh/id_ed25519` for a 2nd private key.
+    
+    The `UseKeychain yes` is the key part, which tells SSH to look in your OSX keychain for the key passphrase.
+    
+4.  That's it! Next time you load any ssh connection, it will try the private keys you've specified, and it will look for their passphrase in the OSX keychain. No passphrase typing required.

+- Abgeschlossenes Modul, in dem man die sämtliche Abhängigkeiten manuell auflösen muss um evtl. Störungen zu vermeiden
+## Bevor der Test ausgeführt werden kann
+- Der ChangeDetection Mechanismus muss per Hand auf dem Fixture ausgeführt werden
+- Um die componente aus dem Fixture zu erhalten, muss man nur `fixture.componentInstance` aufrufen;
+
+## Was bedeutet
+- Declarations:
+	- Verwendete Komponenten
+- Providers:
+	- Services 
+## Zugriff auf die Template Komponenten erhalten
+- Sich die Komponente holen: `fixture.debugElement.query(By.css('.title'));` 
+- Zugriff auf das Element: `const element = debugElement.nativeElement;`
+- Prüfen: `expect(element.textContent).toEqual('Test');`
+## Testen des Inputs 
+```typescript
+beforeEach(() => {
+  fixture = TestBed.createComponent(TaskItemComponent);
+  component = fixture.componentInstance;
+  const task = new Task('Test', false);
+  component.task = task;
+  fixture.detectChanges();

+  const debugElement = fixture.debugElement.query(By.css('.title'));
+  const element = debugElement.nativeElement;
+  expect(element.textContent).toEqual('Test');
+});
+```
+Hier gilt es zu beachten, dass die Werte vor der ChangeDetection gesetzt werden müssen!
+## Testen des Outputs
+```typescript
+it('should correctly handle output', () =>{
+  let taskStatus = false;
+  component.toggled.subscribe((task) =>taskStatus = task.status);
+
+  const debugElement = fixture.debugElement.query(By.css('button')); // Damit kann man sich das passende HTML-Element holen
+  debugElement.triggerEventHandler('click', null); // Damit ist es möglich einen Button zu drücken bzw. ein anders Event anzutriggern
+  expect(taskStatus).toBe(true);
+});
+```
+## Testen eines Asynchronen Services 
+```typescript
+describe('TaskListComponent', () => {
+  let component: TaskListComponent;
+  let fixture: ComponentFixture < TaskListComponent > ;
+
+  beforeEach(async(() => {
+    const taskServiceStub = {
