# Preparations
1. replace contents of the `/modules/custom/install/project_upgrades.sql` file with this (replace `52x_` with your table prefix from `/system/config.php`):
```
# r1: Initial Project Task (#TASK_ID)
SELECT SLEEP(2);
SELECT SLEEP(7);
# r2: Another Task (#TASK_ID2)
SELECT SLEEP(65);
SELECT Version
FROM `52x_Modules`;
# r3: Yet Another Task (#TASK_ID3)
SELECT SLEEP(354);
SELECT Version
FROM `52x_Modules`;
```
2. clear contents of `/system/.restricted/project_upgrades.log` file
3. execute `UPDATE `52x_Modules` SET AppliedDBRevisions = NULL;` (replace `52x_` with your table prefix from `/system/config.php`) database query
# Test 1 itself (takes 7-8 minutes to execute !!!)
1. run the `php tools/run_event.php adm:OnDeploy b674006f3edb1d9cd4d838c150b0567d` script
2. confirm, that contents of SQL-related part of deployment script output looks like this:
```
# r1: Initial Project Task (#TASK_ID)
SELECT SLEEP(2) ... OK (1) *Time*: 2s
SELECT SLEEP(7) ... OK (1) *Time*: 7s
# r2: Another Task (#TASK_ID2)
SELECT SLEEP(65) ... OK (1) *Time*: 1m 5s
SELECT Version FROM `52x_Modules` ... OK (7) *Time*: 0s
# r3: Yet Another Task (#TASK_ID3)
SELECT SLEEP(354) ... OK (1) *Time*: 5m 54s
SELECT Version FROM `52x_Modules` ... OK (7) *Time*: 0s
Total SQL Time: 7m 8s
```
3. confirm, that from the above output:
* the `*Time*: 2s`, `*Time*: 7s` and `*Time*: 0s` text is shown in regular green color (as `OK` text before it)
* the `*Time*: 1m 5s` text is shown in cyan bold color
* the `*Time*: 5m 54s` and `Total SQL Time: 7m 8s` text is shown in red bold color
* the `Total SQL Time: 7m 8s` text represents total SQL run time across all executed SQL revisions
4. confirm, that text added into `/system/.restricted/project_upgrades.log` looks like this (execution start/end date/times would be different, but durations must match):
```

# Test 2
1. add up these lines to the `/modules/custom/install/project_upgrades.sql` file (replace `52x_` with your table prefix from `/system/config.php`):
```
# r4: Initial Project Task (#TASK_ID)
SELECT SLEEP(2);
ERROR;
```
2. run the `php tools/run_event.php adm:OnDeploy b674006f3edb1d9cd4d838c150b0567d` script
3. confirm, that the contents of the SQL-related part of deployment script output look like this:
```
# r4: Initial Project Task (#TASK_ID)
SELECT SLEEP(2) ... OK (1) *Time*: 2s
ERROR ... FAILED
SQL Error #1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ERROR' at line 1
Please execute rest of SQLs in this Revision by hand and run deployment script again.
Total SQL Time: 2s
```
4. confirm, that text added into `/system/.restricted/project_upgrades.log` looks like this (execution start/end date/times would be different, but durations must match):
```
