Since PHPUnit 9.5.10 and 8.5.21, PHP deprecations are no longer converted to exceptions by default (`convertDeprecationsToExceptions="true"` can be configured to enable this).
Reference: [https://github.com/sebastianbergmann/phpunit/commit/fac02620f6b38ae54d47fe840e0095e68226a56c Do not convert PHP deprecations to exceptions by default]; [https://github.com/sebastianbergmann/phpunit/blob/9.5.10/ChangeLog-9.5.md<a href="https://core.trac.wordpress.org/ticket/9510">#9510</a>---2021-09-25 PHPUnit 9.5.10 changelog].
Let's unpack this:
Previously (PHPUnit < 9.5.10/8.5.21), if PHPUnit would encounter a PHP native deprecation notice, it would:
1. Show a test which causes a deprecation notice to be thrown as **"errored"**,
2. Show the **first** deprecation notice it encountered and
3. PHPUnit would exit with a **non-0 exit code** (2), which will fail a CI build.
As of PHPUnit 9.5.10/8.5.21, if PHPUnit encounters a PHP native deprecation notice, it will no longer do so. Instead PHPUnit will:
1. Show a test which causes a PHP deprecation notice to be thrown as **"risky"**,
2. Show the **all** deprecation notices it encountered and
3. PHPUnit will exit with a **0 exit code**, which will show a CI build as passing.
This commit reverts PHPUnit to the previous behaviour by adding `convertDeprecationsToExceptions="true"` to the PHPUnit configuration. It also adds the other related directives for consistency.
