Smoke Test App

What to expect in this example?

• This example is expected to exercise the various features of the ESP Insights framework
• As a smoke test, this allows you to validate, by a quick perusal of the ESP Insights dashboard, the functioning of all the high-level features

End-to-End Tests

Lifecycle of the test (Hard reset resets the cycle)

• Device boots up and logs errors/warnings/events in random order every 10 seconds
• Every error/warning/event log with "diag_smoke" tag is associated with an incremental counter
• There's a 30/500 probability that device will crash, this is done for verification of crash
• Device will crash only five times and hard reset will reset the counter to 1
• On sixth boot onwards device will not crash and logs errors/warnings/events and adds heap metrics

Facilitate the Auth Key

In this example we will be using the auth key that we downloaded while setting up ESP Insights account.

Copy Auth Key to the example

const char insights_auth_key[] = "<ENTER YOUR AUTH KEY>";

Enter WiFi Credentials

Inside the example sketch, enter your WiFi credentials in WIFI_SSID and WIFI_PASSPHRASE macros.

Setup

• Build and flash the sketch and monitor the console
• Device will eventually crash after some time
• Before every crash you will see below log print

E (75826) diag_smoke: [count][7] [crash_count][1] [excvaddr][0x0f] Crashing...
// [count][7]: count associated with the log
// [crash_count][1]: This is the first crash since device boot up, this number will increment as the crash count increases
// [excvaddr][0x0f]: Exception vaddr, will see this in crash verification part below

• You'll see five crashes([crash_count][5]) and after that device will not crash and will keep on logging and adding metrics
• Onwards this point keep device running for more than 30 minutes
• Now we are all set to visit the dashboard
• Select the node-id printed on the console, look for the below log. It is printed early when device boots up
