Add E2E test of `MessageEditHistoryDialog` #10406

luixxiul · 2023-03-18T17:17:27Z

This PR intends to add E2E test of MessageEditHistoryDialog.

The main intention of this PR is to make sure that EventTiles on the dialog keep being rendered in the same way after mx_EventTile:not([data-layout=bubble]) is removed from _EventTile.pcss.

Closes element-hq/element-web#24902

For #9033 (checking EventTiles on MessageEditHistoryDialog)

type: task

Thank you for your contribution @luixxiul

Please have a look at my comments. I am happy to discuss any of them if you have a different opinion

+                // Assert that the edited message is rendered
+                cy.get("li:nth-child(2) .mx_EventTile").within(() => {
+                    cy.get(".mx_EventTile_content").within(() => {
+                        cy.get(".mx_EventTile_body").should("have.text", "Meassage");


Can you add a comment why it is „Meassage“ here?
Took me some moments to understand ⌛

Ah right, it should be noted (as Message and Massage and Meassage are all resemble :-D)

This commit b930982 added a comment to explain it.

weeman1337 · 2023-03-23T08:07:00Z

cypress/e2e/editing/editing.spec.ts

+        const percyCSS = ".mx_MessageTimestamp { visibility: hidden !important; }";
+
+        // Take a snapshot
+        cy.get(".mx_Dialog .mx_MessageEditHistoryDialog").percySnapshotElement("Message edit history dialog", {


Are all the CSS checks probably unnecessary if a snapshot is taken here?
If we change the CSS structure this test will fail, even if the resulting view is the same.
In my opinion we should me more interested about the result here.

I would agree with that checking these CSS styles of .mx_EventTile is unnecessary here, as they are not overridden by _MessageEditHistoryDialog.pcss.

Rather, this line below should be checked in case of a regression after removing !important flag eventually, considering Percy test is not going to be executed on each commit:

matrix-react-sdk/res/css/views/dialogs/_MessageEditHistoryDialog.pcss

Line 57 in 5c47142

padding-top: 0 !important; /* Override mx_EventTile:not([data-layout="bubble"]) */

Since we do not have a Percy test for timestamps yet (timestamps are hidden to prevent a flaky result), checking their style rules should be worth. I cannot remember exactly when, but I think the position has regressed once due to an issue related to CSS style rules inheritance.

This commit 203c8c8 addresses this. It removes redundant checks, saving ones for style rules which are hard to detect or cannot be detected with a snapshot.

weeman1337 · 2023-03-23T08:08:05Z

cypress/e2e/editing/editing.spec.ts

+            widths: [704], // See: .mx_Dialog_fixedWidth max-width
+        });
+
+        cy.get(".mx_Dialog").within(() => {


Is it possible to join the three within?

Something like

cy.get(".mx_Dialog .mx_MessageEditHistoryDialog li:nth-child(2) .mx_EventTile").within(() => {

(may also apply to other places)

I found there were cases which actually should be joined. Working on it..

This commit 5c58427 addresses this. It does not join every within for readability and to clarify the relationship between mx_TextInputDialog and mx_MessageEditHistoryDialog under mx_Dialog.

weeman1337 · 2023-03-23T08:18:33Z

cypress/e2e/editing/editing.spec.ts

+                });
+
+                // Assert that the edited message is gone
+                cy.get("li:nth-child(3) .mx_EventTile").should("not.exist");


It would probably be better to check for the non-existence of „Meassage“ here.
The test already heavily relies on CSS structure.
At least in this particular place it can be avoided.

I'd agree, let me check how it should be changed...

This commit a457fd0 addresses this.

weeman1337 · 2023-03-23T08:21:47Z

cypress/e2e/editing/editing.spec.ts

+        // Send "Message"
+        sendEvent(roomId);
+
+        cy.get(".mx_RoomView_MessageList").within(() => {


Can you try to extract shared code to their own functions?
This would make the tests better maintainable.

I've added some functions:

editLastMessage()

clickButtonRemove()

clickButtonViewSource()

clickEditedMessage()

luixxiul · 2023-03-23T10:32:57Z

cypress/e2e/editing/editing.spec.ts

+                    .should("have.css", "position", "absolute")
+                    .should("have.css", "inset-inline-start", "0px")
+                    .should("have.css", "text-align", "center");
+                cy.get(".mx_EventTile .mx_EventTile_content").should("have.css", "margin-inline-end", "0px");


This line also should be checked because this margin value is specific to the message edit history dialog (See this line for comparison) and it is difficult to detect a regression with a snapshot because text-align is not set to justify, which makes it hard to judge whether the margin setting is really respected or a line is wrapped just because of the length of a word, even if we use a sentence long enough to be wrapped as an example.

For comparison, languages such as Chinese/Japanese/Korean do not have the concept of wrapping a sentence based on the word length, nor hyphenation, therefore any sentence uses every space available inside a line before being wrapped (ie. the same number of characters on each line inside a paragraph), which essentially means that every wrapped sentence is aligned to be justified. This it not perfectly correct, but you could regard CJK characters as monospace in most cases. Therefore checking the margin here makes sense for those languages.

This also means that using a sample text in CJK would make it unnecessary to check this value, but I think it is not practical, considering the possibility of outputting tofu characters if your computer does not have a CJK font, etc., which increases the possibility of flaky test results.

This should not be necessary as we start with a fresh account every time.

That is right. It was removed by 952f370.

@luixxiul can you push an empty commit to trigger CI again with Percy?
