+In Angular use describe statement to separate unit tests, template shallow tests and integration tests:
+
+```javascript
+describe('unit tests', () => {
+  describe('[unit of work]', () => {
+    describe('when [scenario/context]', () => {
+      it('should [expected behaviour]', () => {
+      });
+    });
+  });
+});
+
+describe('template shallow tests', () => {
+  describe('[unit of work]', () => {
+    describe('when [scenario/context]', () => {
+      it('should [expected behaviour]', () => {
+      });
+    });
+  });
+});
+
+describe('integration tests', () => {
+  describe('[unit of work]', () => {
+    describe('when [scenario/context]', () => {
+      it('should [expected behaviour]', () => {
+      });
+    });
+  });
+});
