[Security Solution] Adds Cypress test for index action in detection rules #141069

MadameSheema · 2022-09-20T12:18:04Z

Summary

In this PR we are adding a test to validate that an index action can be added during the rule creation and that the action is properly triggered.

In order to do that, we have extended the object/connectors.ts file creating a new interface, called IndexConnector, which contains all the information needed to create an index connector. We have also created the Connectors type that would be used when creating a rule with actions.

In this test we are creating the rule from the UI to include also the creation of the action. The main focus of the test is to check that the action works correctly, that is why we don’t need a rule with all the fields, we just need a rule with the mandatory field needed on the UI to make also the test execution faster.

To be able to have a rule with just the UI mandatory fields, we have refactored the CustomRule interface to make optional some of the current fields, forcing us to refactor also the methods where some of those fields are used. A part from the refactor, we have extended the interface, with the Actions field.

The new test performs the following actions:  

Clean any possible data that may impact our test on the before hooks. 
Creates an index we will need to have in elastic search to be able to create the index action.
Creates a custom rule with an index action
Once the rule is executed checks that the document with the expected JSON has been correctly indexed.

Alright, I ended up posting a ton of comments, sorry about that :)

One general comment: my expectation was that it should be enough to cover action execution at the integration test level - just like it's done for the alerts generation logic for every rule type.

Scenario: Rule executes successfully with added action (1 integration)

But I'm not going to ask to remove this new e2e test - I think it's also good to have one at the e2e level!

x-pack/plugins/security_solution/cypress/objects/rule.ts

+  runsEvery: getRunsEvery(),
+  lookBack: getLookBack(),


I noticed that runsEvery equals 1 second by default.

// Default interval is 1m, our tests config overwrite this to 1s // See https://github.com/elastic/kibana/pull/125396 for details const getRunsEvery = (): Interval => ({ interval: '1', timeType: 'Seconds', type: 's', });

What's the reason for having such a short interval?

I think for most of the tests where we need to run a rule, we need to run it only once in order to verify something. This means we could set the interval to a large value like 24 hours.

If we use a very short interval in e2e tests, this can:

create unnecessary load (Alerting Framework needs to schedule rules all the time while tests are running)

introduce unexpected race conditions between a test and Kibana running and re-running rules in the background

ultimately make the tests more flaky

I don't remember why we did it like that, originally for sure that was a reason behind. Good to have revisited this then :)

x-pack/plugins/security_solution/cypress/tasks/api_calls/rules.ts

        description: rule.description,
-        interval: `${rule.runsEvery.interval}${rule.runsEvery.type}`,
-        from: `now-${rule.lookBack.interval}${rule.lookBack.type}`,
+        interval: `${rule.runsEvery?.interval}${rule.runsEvery?.type}`,


This will render it to undefinedundefined if rule.runsEvery is nullable. This is why I'm skeptical about making most of the rule fields optional in the CustomRule interface.

+    const riskScore = rule.riskScore != null ? parseInt(rule.riskScore, 10) : undefined;
+    const severity = rule.severity != null ? rule.severity.toLocaleLowerCase() : undefined;


And we also have to check those fields for null all the time...

+  cy.request('POST', `${kibanaIndexUrl}/_delete_by_query?conflicts=proceed`, {
+    query: {
+      bool: {
+        filter: [
+          {
+            match: {
+              type: 'action',
+            },
+          },
+        ],
+      },
+    },
+  });
+};


It would be great to extract all API calls from this common file to the corresponding files under x-pack/plugins/security_solution/cypress/tasks/api_calls

@xcrzx @banderror lots of thanks for your thorough revision!!! :)

I believe it has helped a lot to put the focus on some pain points we have in general that need to be tackled in order to have a more robust and maintainable test suite. I'll write a ticket to collect all this information and I'll share it with you to gather more ideas.

Thanks!

The test now looks perfect, and thank you @MadameSheema for addressing so many comments!

I'll write a ticket to collect all this information and I'll share it with you to gather more ideas.

Please do, that would be awesome!

I'd like us to have ticket(s) for the following ideas:

Reusing existing rule schema in Cypress tests (comment)
Making tests driven by code instead of data; getting rid of optional properties in data (comment, comment, comment)
Cleaning up duplicate properties in data (comment, comment)
Setting a large default rule interval (comment)
Extracting some code from tasks/common into separate files (comment)

Let me know if I can help with writing them.
