Inspections. What is new in 2022.2?

This page provides the list of changes in Qodana inspections as of version 2022.2.

Qodana for JVM and Qodana Community for JVM

New inspections

Inspection name	Severity	Description
`RegExpRedundantClassElement`	Weak warning	Redundant `\d`, `[:digit:]`, or `\D` class elements. The `[\w+\d]` regular expression can be replaced with `[\w+]` because `\w` already includes `\d`.
`MarkdownIncorrectlyNumberedListItem`	Warning	Incorrectly numbered list item. Marks an ordered list like `1. 2. 4.` as inconsistently numbered. After rendering, this list is displayed as `1. 2. 3.`, but the inconsistency makes editing the source code harder.

RegExpRedundantClassElement

Weak warning

Redundant \d, [:digit:], or \D class elements.

The [\w+\d] regular expression can be replaced with [\w+] because \w already includes \d.

MarkdownIncorrectlyNumberedListItem

Warning

Refactored inspections

In 2022.2, several Kotlin and JUnit inspections were refactored.

Inspection name	Severity	Description
`OverridingDeprecatedMember`	Disabled; error	Was renamed for `OverrideDeprecatedMigration`
`MainFunctionReturnUnitInspection`	-	Check for the `@Test` annotated methods was moved to `JUnitMalformedeclaration`
`JUnitMalformedDeclaration`	Warning	Works only for Kotlin. Reports JUnit test member declarations that are malformed and not recognized by the JUnit test framework. Such declarations could result in non-executed tests or lifecycle methods.

Severity

Description

OverridingDeprecatedMember

Disabled; error

Was renamed for OverrideDeprecatedMigration

MainFunctionReturnUnitInspection

Check for the @Test annotated methods was moved to JUnitMalformedeclaration

JUnitMalformedDeclaration

Warning

Works only for Kotlin.

Reports JUnit test member declarations that are malformed and not recognized by the JUnit test framework. Such declarations could result in non-executed tests or lifecycle methods.

Several of the old inspections were disabled by default. Starting from 2022.2, they are enabled by default, and there is no way to disable them individually.

Inspection name	Description
`TestMethodIsPublicVoidNoArg`	Marks test methods that are annotated with `@Test` but do not have the required signature.
`StaticSuite`	The `suite()` method is not declared as static
`BeforeClassOrAfterClassIsPublicStaticVoidNoArg`	Malformed `@BeforeClass`, `@BeforeAll`, `@AfterClass`, or `@AfterAll` method. Prior to 2022.2, this inspection was disabled.
`BeforeOrAfterIsPublicVoidNoArg`	Malformed `@Before` or `@After` method. Prior to 2022.2, this inspection was disabled.
`JUnit5MalformedExtensions`	JUnit 5 malformed extension registration
`JUnit5MalformedNestedClass`	JUnit 5 malformed `@Nested` class
`Junit5MalformedParameterized`	Malformed parameterized tests. Prior to 2022.2, this inspection was disabled.
`JUnit5MalformedRepeated`	JUnit 5 malformed repeated test
`JUnitDatapoint`	Malformed `@DataPoint` field. Prior to 2022.2, this inspection was disabled.
`JUnitRule`	Malformed `@Rule` or `@ClassRule` field. Prior to 2022.2, this inspection was disabled.
`MalformedSetUpTearDown`	Malformed `setUp()` or `tearDown()` method. Prior to 2022.2, this inspection was disabled.
`UnconstructableTestCase`	Reports JUnit test cases that cannot be constructed because they have an invalid constructor. Test cases like these will not be picked up by the JUnit test runner and will therefore not execute. The inspection severity is `Warning`.

Enabled inspections

Inspection name	Severity	Description
`RegExpSimplifiable`	Warning	A regular expression like `[\wa-z\d]` can be simplified to just `\w` because it already includes `a-z` as well as numerals.
`RegExpSuspiciousBackref`	Weak warning	A regular expression like `\1(abc)` cannot match anything because `\1` refers to `abc` that is not yet defined when evaluating `\1`. This inspection prevents simple typos in regular expressions, speeding up the editing experience.
`BulkFileAttributesRead`	Disabled; warning	The 'Files.readAttributes' bulk call can be used instead of multiple file attribute calls
`SlowListContainsAll`	Warning	Call to `list.containsAll` may have poor performance
`IllegalDependencyOnInternalPackage`	Disabled; error	Illegal dependency on internal package
`KotlinPlaceholderCountMatchesArgumentCount`	Warning	Number of placeholders does not match number of arguments in logging call
`NonExhaustiveWhenStatementMigration`	Disabled; warning	Non-exhaustive `when` statements will be prohibited starting from version 1.7
`RedundantScheduledForRemovalAnnotation`	Warning	Redundant `@ScheduledForRemoval` annotation
`ReplaceOnLiteralHasNoEffect`	Warning	Replacement operation has no effect

Qodana for PHP

New inspections

In version 2022.2, the Qodana for PHP linter obtained several new inspections.

Inspection name	Severity	Description
`RegExpRedundantClassElement`	Weak warning	Redundant `\d`, `[:digit:]`, or `\D` class elements
`MarkdownIncorrectlyNumberedListItem`	Warning	Incorrectly numbered list item. Marks an ordered list like `1. 2. 4.` as inconsistently numbered. After rendering, this list is displayed as `1. 2. 3.`, but the inconsistency makes editing the source code harder.
`PhpIntRangesMismatchInspection`	Warning	Number range mismatch. Marks return statements containing numerals outside the range, for example, in `returns int<0,10>`. Also works for fields, field constructors, and function calls.
`PhpVarTagWithoutVariableNameInspection`	Weak warning	Type tag without a variable name. The `@param string` PHPDoc snippet is redundant, and it should be either removed or replaced with `@param string $argument` explaining that the argument is a string.
`PhpLoopCanBeReplacedWithStdFunctionCallsInspection`	Weak warning	A typical loop consisting of three lines can be replaced with the `in_array()` or `array_key_exists()`.
`PhpPregSplitWithoutRegExpInspection`	Weak warning	The `preg_split()` function can be replaced with `explode()` function.
`PhpCombineMultipleIssetCallsIntoOneInspection`	Informational	Multiple `isset` calls like `isset($var1) && isset($var2)` can be replaced with a single call like `isset($var1, $var2)`.

`PhpEchoOpenTagInspection`	Informational	The verbose `<?php echo` can be replaced with `<?=`.
`PhpAccessStaticViaInstanceInspection`	Weak warning	A class static member is accessed via an instance. Similar to Java, a class static member should not be accessed via an instance expression because that would mean that it might be different for each instance.
`PhpMockeryInvalidMockingMethodInspection`	Error	Invalid Mockery mocking target In Mockery tests, methods cannot be private. If protected, they must be specifically enabled using `shouldAllowMockingProtectedMethods`.
`BladeUnpairedParenthesesInStringLiteral`	Error	Parse error due to unpaired parentheses in string literals. Early detection of unpaired parentheses in string literals that are later parsed by the Blade template engine.

Enabled inspections

Inspection name	Severity	Description
`RegExpSimplifiable`	Warning	Regular expression can be simplified. A regular expression like `[\wa-z\d]` can be replaced with `\w` because the latter already includes `a-z`, as well as numerals.
