方法详细资料

assertEqualsVerbose

public static void assertEqualsVerbose(String expected,
                                       String actual)

quoteForJava

public static String quoteForJava(String s)

Converts a string (which may contain quotes and newlines) into a java literal.

For example,

 string with "quotes" split
 across lines

becomes

 "string with \"quotes\" split" + "\n"
   + "across lines"

toJavaString

public static String toJavaString(String s)

Converts a string (which may contain quotes and newlines) into a java literal.

For example,

{code
 string with "quotes" split
 across lines}

becomes

 TestUtil.fold("string with \"quotes\" split\n",
     + "across lines")

fold

public static String fold(String... strings)

Combines an array of strings, each representing a line, into a single string containing line separators.

escapeString

public static String escapeString(String s)

Quotes a string for Java or JSON.

escapeString

public static StringBuilder escapeString(StringBuilder buf,
                                         String s)

Quotes a string for Java or JSON, into a builder.

quotePattern

public static String quotePattern(String s)

Quotes a pattern.

correctRoundedFloat

public static String correctRoundedFloat(String s)

Removes floating-point rounding errors from the end of a string.

12.300000006 becomes 12.3; -12.37999999991 becomes -12.38.

getJavaMajorVersion

public static int getJavaMajorVersion()

Returns the Java major version: 7 for JDK 1.7, 8 for JDK 8, 10 for JDK 10, etc. depending on current system property java.version.

getGuavaMajorVersion

public static int getGuavaMajorVersion()

Returns the Guava major version.

getJavaVirtualMachineVendor

public static String getJavaVirtualMachineVendor()

Returns the JVM vendor.

getBaseDir

public static File getBaseDir(Class<?> klass)

Returns the root directory of the source tree.

outOfOrderItems

public static <E extends Comparable<E>> SortedSet<E> outOfOrderItems(List<E> list)

Given a list, returns the number of elements that are not between an element that is less and an element that is greater.

hasMessage

public static boolean hasMessage(Throwable t,
                                 String substring)

Checks if exceptions have give substring. That is handy to prevent logging SQL text twice

rethrow

public static <E extends Throwable> RuntimeException rethrow(Throwable e)
                                                      throws E extends Throwable

Rethrows given exception keeping stacktraces clean and compact.

抛出:

E extends Throwable

rethrow

public static <E extends Throwable> RuntimeException rethrow(Throwable e,
                                                             String message)
                                                      throws E extends Throwable

Rethrows given exception keeping stacktraces clean and compact.

抛出:

E extends Throwable
