String Helpers

areSame(a: str | None, b: str | None) → bool

Use areSame() to assert that two strings contain the same characters in the same order.

Example

from punit import strings

a = 'hello'
b = 'hello'
c = 'world'
d = None

assert strings.areSame(a, b)
assert not strings.areSame(b, c)
assert strings.areSame(a, a)
assert strings.areSame(None, None)
assert not strings.areSame(a, None)
assert not strings.areSame(None, b)

isNoneOrEmpty(string: str | None) → bool

Use isNoneOrEmpty() to assert that a string is None or empty.

Example

from punit import strings

a = 'hello'
b = ''
c = None

assert strings.isNoneOrEmpty(a)
assert strings.isNoneOrEmpty(b)
assert strings.isNoneOrEmpty(c)
assert not strings.isNoneOrEmpty(a)
assert not strings.isNoneOrEmpty(b)

isNoneOrWhitespace(string: str | None) → bool

Use isNoneOrWhitespace() to assert that a string is None or whitespace.

Example

from punit import strings

a = 'hello'
b = ' \t'
c = None

assert strings.isNoneOrWhitespace(a)
assert strings.isNoneOrWhitespace(b)
assert strings.isNoneOrWhitespace(c)
assert not strings.isNoneOrWhitespace(a)
assert not strings.isNoneOrWhitespace(b)
